I spoil myself too much

So... I just splurged on an iPod Touch! A used one but it works like new (I'm covering up the scratches on the back with a case!)

It's a 3rd gen - mostly because I don't need the camera or video that comes with the new ones. And it's cheaper! I got 32g this time because I kept running out of space on my old 2nd gen nano.

I need some app suggestions!

I already have 4square, games like mancala and yahtzee, and a pdf reader!

Preferably free but if it's something TOTALLY AWESOME that I can't live without, I'd probably buy it :D

Please halp!
