I don't care so much about iWatches, but I'm not getting one until they stop looking so dorky.
As the owner of a calculator watch, I'm clearly unconcerned about fashionability of the device if it provides the function that I need. But you know what the great thing about that old Casio calculator watch was? I could buy one battery for it and it would get me through a year and a half or two years of daily use easily. And the odds of it deciding to explode after something as likely as crashing on a bicycle or getting caught in a car door are basically nil so long as it's not being used as a bomb timer. I'm holding out on smart watches until smart watches are that affordable, that durable and have that kind of battery life. Bad enough my phone barely has more battery life than my laptop.
