If I only had a device that tells time, tracks steps. collects information, checks pulse, supports bidirectional communication in text, Email, video and voice formats, has a fat battery ( and requisite chargers with unique connections - Gah! ), does GPS, Traffic, predicts weather, has a huge developer base and global acceptance. Wait, I do.... Cell phone... many of you have them now. Will the FanBoy effect be enough to make 20,000,000 sales? The only different thing (it seems) is a continual proximity to the skin (might be niche?) for blood chemistry monitoring (There I said it.. prior art, though it seems obvious to me). I have a cell phone, and can get another in a variety of sizes...I am past the watch phase. Think most of us are, unless it does something that much better.. Do i want High def on a 1"x5/8" screen? Nope. Will wait till I get home for my garden variety 52" TV. It is interesting how MP3 Tech was scooped up and make into a proprietary format, but am skeptical that the same will happen for a format most of us keep in the drawer these days. Maybe medical monitoring will be the niche?
