GPS vs. cell-phone navigation

Faceoff: GPS navigator vs. cell-phone navigation

Drivers looking for an electronic navigational assistant have more choices than ever these days. Basic dedicated GPS navigators can be found for less than $100, and they are still a wise choice if you don't mind carrying a single-purpose device. Personal navigation devices (PNDs) are ready to go right out of the box, with a mount and charger included. Plus, they are easy to use and can be shared with family or friends.

Smart phones are an increasingly popular navigation option, especially among models that come with turn-by-turn guidance built in. Other phones require purchase of a downloadable navigation app or a service subscription. In our tests, we have found that the best navigation applications are made by well-known GPS companies like Navigon, TomTom, and Magellan. These apps look and function much like a standalone GPS unit.

Virtually any new cell phone is now capable of giving directions, whether it's smart or otherwise. Cell-phone providers, such as ATT and Verizon, offer turn-by-turn directions for a fee, usually about $10 per month or $3 per day. This form of navigation aid is handy for a vacation or if you only need directions occasionally.

If you choose to go with a phone for guidance, keep in mind that a phone with a large screen will be easier to read and use on the go, and it can come closest to the performance of a portable GPS unit. But with any phone, you'll have to buy a mount and car charger separately, which can add another $50 or so. A good navigation app adds another $50, making the combined cost about as much as a dedicated device. And if you opt for a subscription plan, instead of a downloaded application, the monthly fee can quickly add up to more than the cost of a basic GPS in just a year.

Which is solution right for you?

Here’s a quick guide to the pros and cons of approach:
Portability: Using your cell phone means you have one less thing to lug around. On the other hand, you have to mount it to the windshield every time you use it, which could be more hassle than a GPS device that you leave mounted all the time or at least in between stops (in less theft-prone areas, of course).
Advantage: Depends on your situation.

Dependability: Any system will likely get you to your destination. But one big limitation of most cell phones (typically subscription based navigation) is that if you’re in an area with a poor cellular signal, the navigation system won’t work reliably. Models that load maps into the unit’s memory are an exception. Also, using navigation can run down a cell-phone battery, so you’ll want to plug it in when in use. A GPS device tends to lose much of its energy when sitting unused for a few day, meaning that in practice, a dedicated device will likely need to be plugged-in when in use.
Advantage: GPS.

Up-to-date info: The map and route information that cell phones download is always the most current version supplied by the map provider. With GPS units, you have to buy map updates and install them yourself. These can cost $50 to $80.
Advantage: Cell phone. Manufacturers are now offering different pricing plans to get updated maps such as one to four updates in one year or lifetime updates. (This advantage may be diminishing for cell phones.)

Displays and buttons: The large touch screens on GPS navigators are easy to read and use. Most cell phones have much smaller screens and small, hard-to-use buttons. Of course, some newer smart phones have good touch screens that are about the same size or larger than GPS devices.
Advantage: GPS and some smart phones.

Cost: You can buy a good GPS device for $100 to $250. And once you’ve bought it, you’re good to go. With cell phones, you have to pay an ongoing subscription fee (unless you pay by the day), whether it’s for a dedicated navigation service ($10 per month) or a cellular data connection (often about $30 per month premium). These costs can quickly add up to more than you’d pay for the GPS unit. A navigation smart-phone app could cost you an additional $30 to $75 but do not carry the monthly fee. Of course, if you have a smart phone with a built-in nav program and you’re already paying for a data feed, then navigation doesn’t cost you anything more.
Advantage:
GPS and some smart phones.

Accessories: All GPS navigators come with a mount and an in-car charger. But you’ll have to buy them separately for a cell-phone, which could cost you another $50 or more.
Advantage: GPS.

Choosing a navigation solution can be tough. Clearly, there are a lot of pros and cons to consider. Remember, a key factor is what you already have. If you own a large-screen cell phone, it may make sense to enhance that as an all-in-one device with an app and mount.

If it is time to upgrade a phone, you have a more options. But remember, you can’t readily share a phone.

For a family looking to limit expenses and doesn’t need a pricey smart phone, then a dedicated device would be the most cost-effective solution.

What You Need to Know When Buying a Tablet Computer

by John Marrin

Wired.com: Full Article

The world is flat, after all.

At least, the gadget world is — this year. After Apple broke open the tablet market with the iPad in early 2010, nearly every major manufacturer announced its own plans to make a flat, keyboard-less wonder.

That’s not surprising, since tablets have much to recommend them.

Thinner and lighter than a netbook, tablets easily pack into a small bag or purse. They offer super-simple browsing and e-mail reading capabilities. While they lack keyboards, they’re easier to type on than a tiny smartphone. And they can stream audio and video, making them excellent portable media devices.

However, navigating the tablet market can be tricky. The difficulty of making a usable, well-built tablet with long battery life is illustrated by the many months it took manufacturers to come up with credible alternatives to the iPad.

And while the iPad still leads the market by a mile, there are now options if you want to get a device that wasn’t conceived in One Infinite Loop.

If you’re shopping for one of these portables, here’s a quick rundown of buying decisions and features you should consider before pulling the trigger.

Screen

Screen is, arguably, the most important factor in your purchasing decision. In general, you’ll probably be more comfortable typing and tapping on a larger screen — even a half-inch bigger can make a significant difference. However, some users might want their tablets to be more portable, and a big screen adds more weight and bulk. Dell’s Streak comes in on the smaller end of the scale with a 5-inch screen, making it more of an oversized smartphone, while the Samsung Galaxy sports 7 inches. For those who want as much real estate as possible, the Archos 101 has a 10.1-inch screen that outsizes even the iPad’s generous 9.7-inch screen. Meanwhile, Toshiba’s Libretto sports dual 7-inch displays in a funky clamshell design.

You should also look at dot pitch, or the screen’s native resolution measured against the size. More pixels per square inch generally means a sharper picture for movie-watching and clearer text for reading. Of course, how a screen looks is largely dependent on color depth, contrast and brightness.

Outside of stated specs, which can be misleading, try to take a tablet for a test-drive to check the screen’s capabilities. Definitely check to see how responsive the screen is to your touch — after all, you’ll be poking at it constantly. Make sure brightness is turned up all the way so you’re evaluating each tablet at its best. Lastly, keep in mind that a sleek, glossy screen might look great in even lighting, but can cause horrible glare in bright light or sunlight, especially once you’ve smudged it up with your fingers.

Tip: A clear adhesive screen protector can mitigate some glare, as well as protect the screen from scratches. If you plan on replacing a laptop with a tablet for heavy-duty daily use, consider carrying a microfiber cloth and some screen-cleaner fluid for more stubborn spots. Wiping your tablet screen with tissues or napkins (or on your pants) can make smudges worse and leave behind lint.

Wireless Connections

Nearly every tablet is Wi-Fi-capable, but check which: Some models only support the 802.11b/g spec. This probably won’t be a big deal if you’ll just use your tablet for general computing, but if you plan on doing media-streaming and heavy-duty downloads, look for 802.11n.

A tablet with a 3G cell connection on top of Wi-Fi will let you stay in touch even when you’re out of hotspot range. But consider the coverage in your area, as well as the details of the contract.

The iPad 3G patches into AT&T, while the Samsung Galaxy Tab is available through Sprint. The upside? You can get online anywhere that wireless service provider has a signal. The downside? The data plans are costly and sometimes (but not always) come with a contract.

You also might want to consider a model with GPS, since a tablet’s larger screen size makes it an easier-to-read travel companion than a smaller GPS-enabled phone. If you’re looking at the iPad, you’ll have to shell out for the 3G model if you want the GPS.

Bluetooth can be useful, as well. For one, it offers easy wireless data transfer. Connecting a Bluetooth headset or headphones can also be useful for chatting and listening to music. You may also want to use a Bluetooth keyboard for longer typing chores.

OS and Apps

The main choices here are Apple’s iPhone-proven OS and Google’s up-and-coming Android. Each has advantages and drawbacks.

Apple’s iOS offers a massive app store as well as rock-solid hardware and software integration, but lacks support for Adobe Flash, limiting the web experience a bit.

There’s a better selection of Android tablets to choose from made by a variety of companies, but the OS isn’t quite as refined as Apple’s. In addition, the Android app market has a lot of great apps, but the quality control isn’t as tight as Apple’s. This cuts two ways: There are plenty of great apps that are the same as, or similar to, offerings for the iPad, but Android apps can be buggy.

Storage

The one thing that will always be true about storage is that you can never have enough of it, especially if you plan on using your tablet as an entertainment device for movies and music. Yet the flash-based RAM used in most tablets is expensive, meaning you’ll have to settle for a few GB at most. A tablet with an SD or microSD slot is a big boon, since it will let you upgrade your storage by adding a removable memory card.

Inputs and Outputs

Since tablet PCs are fairly lean devices, connections are usually restricted to the usual 3.5mm headphone jack and a USB port. Apple’s vaunted iPad doesn’t even have a USB port, so you’re limited to gadgets that work with its proprietary iPod connector.

A select few will have additional ports like HDMI out, letting you show videos or photos on a TV. Ask yourself if you’ll be using your tablet as a desktop/notebook replacement. If the answer is yes, then these additional ports will probably come in handy.

If a tablet you want doesn’t have all the connections you desire, there are a handful of external port adapters for tablets. For instance, the Archos 9 tablet offers a detachable port replicator that gives you VGA out, ethernet and a couple of USB ports, while Apple has a dock-to-VGA connector for connecting to a full-size monitor, and a camera connection kit for uploading images from your camera to your iPad.

Speakers

Sure, most folks use headphones, but there will inevitably be times when you’ll want to keep your ears unplugged. Built-in tablet speakers won’t sound great, but if you’re shopping in a brick-and-mortar store, take the speakers for a spin to see how far you can push them.

Camera

Even if you already have one on your phone (which you’ll probably have with you, anyway), an extra camera is always handy. Editing photos on a tablet’s larger screen is also inherently easier. Measuring a camera by mexapixels is one thing, but remember that real video and photo quality comes from accurate color and the ability to change camera settings for a particular shot. The Samsung Galaxy Tab even has two cameras — one front-facing, one rear-facing — so you can video chat or simply record yourself. The iPad, however, does not have a camera at all.

It Won’t Replace Your PC

Tablets might be the future of portable computing, but we interact with them in a profoundly different way than with smartphones or laptops. Tablets are ideal for web-surfing, watching films and TV shows, doing some light e-mail, reading magazines and newspapers. They’re fit for consuming.

But for creating content they’re lackluster and underpowered compared to even the most bare-bones laptop.

Tablets may revolutionize the way we interact with the web and other media. Just don’t expect one to serve as your primary computer.

Package Delivery Failure VIRUS

 

Be wary of emails from UPS, USPS, FedEx, etc, claiming they have a package for you that requires you to open a file attached to the email.  The attachment contains a virus.

http://www.snopes.com/computer/virus/ups.asp

A common (and unfortunately, effective) technique for luring e-mail users into opening virus-launching attachments is to send messages that would appear to be relevant or important to many of their potential recipients. One way of accomplishing this feat is to make the virus-carrying messages appear to come from some type of business entity that many people commonly deal with, such as one of the large Internet auction or retailing sites, or a national bank (or other financial institution), or a major provider of a common service.
