Well, early adopters always have to put up with some inconvenience. Surely things will improve with time though. eInk displays would likely be a huge step forward, and it's likely that less energy hungry electronics will be used once consumers and vendors figure out that this isn't the next platform for Angry Birds (thus you don't need the processing power).

Oh, and please don't mention fashion accessory in the context of watches. I had to argue with a saleslady to buy a women's watch the last time around. At the time, men's watches were these huge glittery things because they were in fashion. (The other extreme were huge chunks of plastic that they called sports watches.) Some of the women's watches were quite handsome though, and quite like men's watches of old. Yet somehow it was considered immoral for a man to buy one because it wasn't the latest fashion trend for men.

(P.S. on the watches dying out bit: maybe it's because I work with younger people, or perhaps it's a city thing, or perhaps it's a Canadian thing, but it's getting kinda hard to find people who wear watches.)
