The best thing about Apple selling this watch now is that it puts them on track to make one half as thick a few years later that really will be aesthetically competitive. Within the decade, smartwatches will undoubtedly be thinner than mechanical watches, but they've gotta start somewhere.

Though I do have to admit that going into this thing, my guess was that they'd be using a new color e-ink display to save battery life, not a "raise your arm to turn it on" sensor.
