Bamboo - basically a cool note taking app, using your own handwriting.
Plants vs. Zombies - an addictive game that I personally cannot stop playing.
Phoster - fun app that lets you make posters (what I'll use these posters for, I have no idea)
Half Tone - LOVE this app. Here's an example of what you can do (it basically cartoon-izes everything)
Air Hockey - It's air hockey...need I say more?
Ultimate Hangman - Um, it's hangman.
Labelbox - let's you add pretty little labels to your pics.
8mm - Takes pretty realistic 8mm movies, allowing you to adjust sound, jumpiness, granularity, etc.
*Not to be confused with the Black Eyed Pea, Apl.de.ap...
