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!"
This is stupid. In addition to the fact that, despite the maddening nature of iDrive, no sane person would just rip it out of their car, I doubt the magnet is strong enough to hold onto the Pre if you hit the breaks or take a sharp curve, which means your Pre will be flying all over the place, unless you drive like grandma.
