iPod Touch Apps

For iPod Touch owners what are the best FREE apps that it has? I've been trying to see if the App Store is really a deciding factor for me in deciding what PMP to get and I've realized I'm too much of a cheap ******* to ever pay for apps. So I need to know what are the best free ones they have.

Just in case you're interested I've seen lots of people's top 10, top 15 free apps and low-cost apps from the app store on youtube. A lot of people seem to agree on what they think is the best of the free stuff.

Ive just purchased myself a refurbished16gb 2nd gen ipod touch from apple and im waiting on it to be delivered. Ive had a look at some decent free apps from videos and already added somethem to itunes e.g cude runner, paper toss, papijump and a few more seem like very addicting games that are free. Im actually selling my psp with custom firmware for it because of its portability(i basically never used my psp out of my house because it was too big). One problem though is every single good free games seem to have another upgraded and better version which costs money.
