They pulled another Apple.
Apple went on and handled Antennagate by saying "oh, death grip happens with all phones" and swiped away the real problem: touching the gap would short the antennas and kill signal reception, which was an iPhone4-only issue.
MS goes "oh, you want your Start Button back? There it goes!" while swiping away the real complaint: "I want my Start MENU back!" coupled with "how do I disable this baby toy UI?"
Hopefully, users will hold on and *not* buy in on Win8 even after these "changes".
