while I agree, as a technophobe, I love the trend we're seeing about incorporating technlogical advancements into everything and the synergy of different tech solutions with eachother for convergent needs. Watches are a bridge that is not going to be easily passed by throwing bigger beefier things at it.
Unlike phones, which when they were new, and early stages, could get away with being big and ugly devices, since you carried them in your pocket and were not intended to be fashion accessories, watches are by primary purpose, a fashion accessory. One of the primary drivers for how well a watch is received is by it's look. Watches are an outward appearance accessory which are seen by everyone.
if the technology isn't there to make a watch that is aesthetically pleasing, then a smart watch isn't going to be a succesfull product. These arent the first attempts at convergence of watch and tech, and most have failed previously because of being large and nighmarish. Who didnt get the AM/FM watch to try out when they were younger? Or the Dick Tracy TV watch? While they were technologically superior, hey all eventually failed because they were primarily tech, and not good looking.
This IMHO is going to be why the Samsung wearable will also be a flop. This is not something you will see business people wanting to wear as they walk around the office. in company meetings, out shaking hands and making deals. Its remiscent of those calculator watches from seiko that math nerds and computer geeks might have worn to math club.
