Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
played with the i770, and i hated the optical mouse thingy. i didnt get the chance to mess with it for an extended period of time, so it might be awesome beyond compare, but i doubt it. i like the form factor, very blackjack/Q
but the omnia is aparently going to be the best thing since sliced bread. a buddy in the company got to play with a tester, and he was very much impressed with it.
and i cant wait for the omnia. it will be nice to have something smaller than my i760
