Mobile Games: FTW or ForNoobs?

What do you guys think about gaming on your mobile phone ? I think it's a great alternative if you don't have a DS or PSP ! I usualy play on my Sony E. 350 W at school when the teacher isn't coming to class, and I am very pleased with those games ! There are some really interesting titles like PlayMan Extreme (parkour), Spore, Overtaker, Tomb Raider, Family Feud and much more !
So, what do you think, forum, is mobile gaming for noobs or it's a good way to spend some time when you're away from your xbox360 ?

I have played some really fun games on my iTouch. So much fun, in fact, I'm beginning to think of my iTouch as a handheld platform. Still no replacement for a PSP or DS, but it's still very fun. If only it didn't tragically break.

iPod Touch and iPhone perhaps have some cool mobile games. I think Windows Mobile has big potential to be a gaming platform, it just needs more attention, as well as the Zune HD. iPod Touch definitely can be considered a game machine, as long as the quality increases and production values rise.

Meh, Iphone has good games. The average phone has pretty crap games, though on almost any mp4 player (not ipods) you can play snes games Maybe on phones too...

I enjoy quite a selection of iTouch games like Pocket God and Metal Gear Solid Touch.

Mobile games are just for short sessions of gaming. if you're bored, just pull out the ipod for a quick, fun 10 minute game.

I dont like'em except for the Iphone.
