The Final Death call for Windows XP

Microsoft has announced the Windows Xp will no longer be supported after April 8, 2014. I guess they picked the 8th since no one would believe April 1st. http://windows.microsoft.com/en-US/windows/end-support-help What about all the millions of PC's out there with Windows XP? With a number of people, if it still connects to the Internet, they will not upgrade. Many businesses have started migrating to Windows 7 (after deciding Vista as not worth it, sort of like Windows ME, which Microsoft would like to forget). Will this be a big boost for the PC industry as people have to upgrade or will it be a boost for Apple if they go for a new iPad tablet instead of a PC? Time will tell.
