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!"
The software for the MX Revolution on Mac OS X was horrendous; you couldn't tell the side scroll wheel to do anything useful, and now the software doesn't even work in Leopard, so I switched to a G5 that I use without drivers. The new G5 is fantastic, rubber grip and finally 2 side buttons rather than one, and it has a weird new blue finish that I kinda dig.
