What worries me is that Microsoft will do their usual thing of forcing the
hardware vendors to include a copy of Win 8 as part of all their hardware sales and then point to the great sales shown, despite all the systems that come with the backwards upgrade to Win 7 where people wipe Win 8 and load Win 7.
What should be looked at to see if Win 8 is a success is how many copies are sold as retail packs and not with new hardware, and compare that with the rate of past retail sales.
