its not about practicality, not in the real world anyway. it's all about soul, to me at least. i use, on a daily basis, and enjoy, a fine fountain pen, a mechanical wristwatch, it's about the marvel of a micoengineered machine on your wrist. basically, it's all fluff, nothing at all to do w/ practicality. no one needs it, we just want it on an emotional level. all the luxury goods you see, few of them are truly practical, but they make you *feel* good, and that is what they sell. one might argue the same point about a SF using propietary (to the general public) Li batts vs the dollar store special that runs on AA.
