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!"
Unlike UMPC's with desktop Windows, these are actually a practical and usable device for mobile computing - especially in the car. The software base may be lacking - but that could easily change if the device sells.
I'll certainly be buying at least one. As I don't see anything else successfully filling the gap between smartphone-PDAs and laptops. I want it mainly for mapping and information databases. And for me a 7" instant-on pad is just what I need. There's enough software for my needs already - but I appreciate that there does need to be an improvement. The return of pocket office would be a big help imo.
