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!"
These statistics are right, many children do have these mobile phones here, however they're simply hardly used. I've only seen one or two kids with these phones, and even then they were only on strings around their necks.
For the most part, little kids couldnt give a crap and just carry it around because their ultra-paranoid parents tell them to. It's not until they become budding young tokyo-ites that it's a nescessity to email and surf 24/7.
