Your iPod Touch applications

I'm in love with my iPod Touch. I have several games and applications, but I want more :D
What are some of your favorites?

My favorite games thus far are:
Glyph; Diner Dash; Chocolate Shop Frenzy; Sally's Salon; iGotchi; Sol Free; Everest; Bejeweled 2; Little Shop; Herods Lost Tomb.
My favorite apps are:
iNote; Learn; WordPress; MPG; and countless binaural and sleep sounds.

What can y'all recommend?

Why wouldn't you just get an iPhone?

Initially, it was because we didn't have AT&T in our area. Now it's simply too expensive. I use a trac phone for emergencies.
But my hubby says that the iPod touch has more memory for what I need. I love it for playing games and listening to music on the go. And I have a lot of games lol.
