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!"
"(if that's not a "why didn't we think of that?" kind of product, we don't know what is)"
That's precisely the issue. Things like this and the brilliant "turn the phone over to mute it" and "shake the phone while locked to view a text, then shake again to lock it" are simply to brilliant and obvious at the same time to put together for most of us. At this point, "...we don't know what is..." more obvious and brilliant than these things, but hopefully this platform will continue to deliver the obvious and yet make the developers some money for Cheetos, or whatever these freaks eat. :-)
