Pocket Informant is currently the best event/task manager.
I like PocketMoney, TapExpense, and SplashMoney.. but I'd go with PocketMoney for it's speed of use and small features like built in keyboard with basic calculating functions... SplashMoney's great, but it took too long to make entries on the fly. TapExpense is awesome for on the fly entries, but it doesn't support transfers.
Momo and Notebook (Appigo's) are good. I use Momo cause it's easiest to lock my notes.
Photogene, CameraKit, and Photohype are all great.
My favorite games are Uniwar, Galcon, and Chess With Friends.
I'd say Fastlane is the best racer (hard to compare Need For Speed when ALL THE DIRECTIONS, MENUS, AND DIALOGUE ARE IN JAPANESE <-- EA supported English in their Simcity Japanese edition, but not in NFSU).
