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!"
I heard some heresay about there being ads on Android? Is this true? Because if so that would be a HUGE con for me. (It's unfortunate for the Zune HD as well; it looked pretty good.)
No fanaticism please. WinMo with TouchFlo 3D, Android and other open source OSs, and iPhone's OS are all great on the basis of design, usability, and ORGANIZATION. I don't care how far into the OS you can customize, if it doesn't organize and display my data properly, I don't care much for it.
