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!"
Today's high end hardware is low end a couple years from now. Even after my next upgrade (desperately waiting for a quad core notebook), I'll be shutting off services eventually to squeeze out every last bit of power, but you can bet I'll be running Vista a lot of the time. (Linux too, but gamedev has to be done in Windows for the most part...)
