Ever since Google brought out their first batch of Android devices, people around the world decided to take advantage of the new mobile OS and create droid apps for every form of information and entertainment. Not to mention all of the utility and productivity apps for the workplace. While some of the apps cost ninety nine cents and up, there are tons of free ones to choose from as well.

The three app reviews here are just a tiny sample of what to expect when browsing the Android Marketplace. Playing video games has always been a great way to have fun since the early 1980s. Nowadays, gamers like to not only revisit some of their childhood favorites, but play them on a mobile device.

Nesoid Lite is one of the many droid apps that turn your smartphone into an NES emulator. While the app is free, you'll have to find your own games through P2P file sharing. That is like getting a pirated copy through Limewire. If you don't care about getting arrested or sued by Nintendo, you can pick this app up for free. Most droid apps for pictures let you crop, rotate, and add effects.

FX Camera takes it one step further by adding filters to the mix. From Fisheye and Polaroid to even Warhol style, you can create some very interesting pictures to share with your friends via Facebook and Twitter. The only drawback is that you only get up to 6 filters to play around with. However, since the app is free, there is really not much else to complain about. Also, be prepared to laugh out loud when using the fisheye filter. Other than UStream, there are not many decent droid apps that let you show live video from your phone to your friends online.

Qik is an exception to this. This app lets you broadcast live video to anyone via Facebook, Twitter, or even YouTube! Plus, it free. Imagine going to see your favorite soccer team and all of a sudden a riot breaks out after the ref made a bad call. This is the kind of app that would be perfect for these moments. Unless you're an AT and T customer, you can pick this app up for free in the Android Market. As stated before, this is just an example of what you can find among the droid apps out now.

Keep in mind that certain apps require certain versions of Android OS. Check which version your device has loaded on it and then see the tons of apps that AT and T subscribers can't get their hands on, such as Qik. Mainly because they either use up so much data or they are meant for the newest version of Google's mobile OS. The newest smartphone AT&T offers is the HTC Aria, which only runs Android  version 2.1. Beyond that, there are tens of thousands of droid apps to play with.
