Dropbox

Dropbox 

For those who use Dropbox on their desktops already, this app performs pretty much the same function on your phone. With Dropbox, users can upload or download files to their accounts without carrying around a pesky flash drive at all times. The download and upload speeds are quick on 3G, and the app includes several sharing options for files that you have downloaded. This makes for easy transference of files to and from your computer and your Android device.

TripIt – Travel Organizer

TripIt – Travel Organizer 

Travel is complicated. Between flight confirmation numbers, hotel addresses and phone numbers for all of the above, staying organized can entail a hefty wad of paper in your carryon and a lot of wasted time leafing through it all. TripIt stores all your pertinent trip information in a neatly organized form, and can even generate itineraries automatically by e-mailing it confirmations from different travel organizations.

Cab4Me Taxi Finder

Cab4Me Taxi Finder 

A simple outstretched hand will do the trick in midtown Manhattan, but if you’re looking for a cab in less frequented places around the world, Cab4Me will bring them to your feet with the press of a button. By locating you with GPS, it only lists cab companies that service the area you’re in, and even shows details like how many cabs they have available and what forms of payment they’ll accept.

Netflix

Netflix 

If you don’t have a Netflix account, this app won’t pertain to you much, but since that seems to be a minority of folks these days, we’ve added the movie-and-television giant to our list. Users can manage accounts, add items to a queue, or stream shows or movies that are available via Instant Watch. Streaming can be a bit much for the 3G connection we were working with, but if you have a Wi-Fi connection you shouldn’t have any problems. With a good connection and a device with a good-size screen, you’ll have a pretty solid streaming experience.

Qik Video

Qik Video Connect 

Put all the power of the local news station’s video broadcast van in your pocket. Qik allows you to upload live video footage from your phone, anywhere you get sufficient coverage. Broadcast your kid’s sports game to his grandparents or a live Muse concert in Barcelona to the entire Web, all in real time.

Kindle

Kindle 

If you don’t have a Kindle, fret not. Amazon would still like to sell you books through your Android device. Download the app and you can browse and buy from over 900,000 books in the store. Perhaps the best feature, however, is that the app will automatically sync your last read page, bookmarks, notes, and highlights across devices. If you do have a Kindle, this means that you can seamlessly transition from your reader to your phone if you want to carry a lighter load that day.

IMDB Movies & TV

IMDB Movies & TV 

What is life without IMDB? We wouldn’t know anything about the movies without it. Like Flixter, IMDB is a must-have for any fan of movies or TV. Luckily, the Android app for IMDB is faster than the Web site itself. It has all the essential features and looks a lot nicer than the Web version. Android tablet owners get a big-screen experience as well, which is fully customized to the needs of Android Honeycomb. There’s very little reason why you shouldn’t own this app. It will save you time when you are wondering if that’s Liam Neeson across the street or just a really tall, badass dude.
