Recommended iPod touch applications?

Free Apps (check out FreeAppADay.com if you'd like - they have a decent amount of good apps for free mixed in):
FML - if you enjoy reading them. :p
Flashlight - Free "flashlight", also has some fun things to play around with. Super useful if you ever need a bright light.
AppBox Lite - Has some useful Apps like converters, how long until x day, etc. I've found it useful.
BatteryStatus - Gives you a more accurate read of your battery life instead of just guessing what % that bar is at.
Dictionary.com - Pocket dictionary by the website. The free version does have ads, but it's not that bad.
Speller - Free spelling app; also useful
TrippingFest - Fun app where you can draw different things and mess around with reflections of what you draw and stuff.


Also, check out the developer FreeTheApps - they make a bunch of fun/useful apps to play around with.

Paid:
Scrabble - if you enjoy it. They put it on sale every so often, so I got it for $1.
Angry Birds - Totally worth it. $1.
Peggle - Lots of fun. Like $1-3
Plants v. Zombies - PopCap game. Lots of fun (a tad laggy on a few levels, but so worth it). Also like $3.
