If you don't like Apple's record when it comes to what they announce vs. what they ship, you REALLY don't want to look at ANY tech other company
My bets are that the Apple Watch will ship, AND will do more (not less) than shown in October.
I'm critical of Apple because I love their products. I want them to do well and am disappointed when they fall short.
I came from Windows and will never go back. It's a fundamentally flawed product. And the crap from the likes of HP, Dell, etc. make me want to run for the hills.
Who knows how the Apple Watch will do. Cook celebrating in October like it already had iPhone-like sales was uncomfortable to watch (not pun intended). Seemed more like personal vindication that Cook could oversee a new product category than anything else.
