I agree that many of the games for iphone are useless and a waste of disk space, but it all depends on what you are using the phone for. Working in the retail store, I have seen people buy the phone simply because of the lightsaber app. Young teenage girls usually have about four pages of apps that I have never heard of. The great thing about the app store is that there is something for everybody.

 Check out this app called Fireman

It's nicely animated and feels great on the iPhone.
Basically, it's a fun app .

 Big game developers are definitely learning how to make the iPhone do their bidding. 
Just check it out (it costs $0.99):
