1. Gameboid, def great when you're bored.
2. Beautiful Widgets, love the clock widget and toggle widgets.
3. Doubletwist Airsync, so convenient. Just be in wifi with the desktop and agl your music syncs automagically!
4. Texts from last night, always makes me laugh. Basically just drunk texts from college kids
5. Turbo tax snap tax. Only use once a year but it was a 'snap'. Ouch, bad pun.
Those are the only apps I've paid for. Great thing about android, alll the good apps are free!
