That despite technical excellence (I don't think anyone doubts that Apple will produce a high quality part),
Apple has done nothing to show WHY anyone would want one of these. its been said many times in many threads, They did a terrible job at showcasing why you or I would have our lives changed forever by this watch.
Previously, with the iPods, iphones, and iPads, they were able to demonstrate, legitimate real world usage scenarios in which the devices would make a demonstratable impact in your life.
This is not something they've managed to do yet. It's apple fashion for fashion sake. From a functionality standpoint, they haven't delivered anything really above and beyond what elseis out there. They've just done it with the typical apple Fit and finish.
They still haven't explained HOW this will benefit us. Just repeating "it will change your life!" won't actually change our lives
There were more negatives about the Ipod, Ipad, Iphone than positives pre-launch too... So, I'm betting more that people like to whine a lot ;-).
