SPOT watches are attempting to be the central computing device and communicate over a 100Mhz band to MSN Direct service. So firstly the watch won't do much if your not in an area covered by MSN Direct; secondly there's not enough processing power in there to do much anyway.In comparison the iWatch uses the processing power of an iPhone/iPod Touch. You missed the point about it being an iPhoneOS 3.0 PERIPHERAL not a computer in itself like SPOT watches are attempting to be. Comparing wireless coverage; an iWatch inherits (via its Bluetooth connection) the same coverage as the host device (WiFi or cell network) unlike the limited MSN Direct service.
