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!"
It's because of the screen...I do not want to "double-click" to get to everything!! And none of that fancy multi-touch either
And....It's not that thin...for just an all screen phone, its probably one of the thickest.
That is my reasoning....no i am not a nokia hater, I personally own a N82 myself, and people are amazed at how "thick" it is...obviously thin form factor is the only way to go.
