Art Gallery, Wikipaintings, RedditGallery, e-Museum are all cool coffee-table apps
Calculator (I think that’s what it’s called) has finger-tracing recognizing ability to do simple math. It’s more fun than practical.
Load up on finance apps. It’s how I bank, manage my credit cards, pay my insurance, invest money, and monitor cash flow. Mint.com specificallly.
Puzzle Craft (match-3,4,5,… city builder game). Luxtouch (risk), NYT crossword, Quizup (trivia), Army of Darkness are all fun games. Plants vs Zombies 1 is better than 2 imo.
