Best Buy will start preselling upgrade versions of Windows 7 Home Premium for $49 and Windows 7 Professional for $99 via its Web site for only 16 days starting on June 26. It’s not totally clear whether those are standard or promotional prices. Microsoft Senior Vice President Bill Veghte did say in an interview this week that the software maker was considering requests from Vista owners to have a free or cheaper way to upgrade to Windows 7, so perhaps this pre-order option might be that program. My personal opinion is that Windows 7 is going to be a very good operating system. I’ve done beta testing and also testing on the first release and it looks to be a very stable and fast operating system. Compared to the Windows Vista disaster it should be a lot faster with less resources being used. I although won’t be upgrading from Windows XP anytime soon. I’ll continue to play with Windows 7 in VMWare workstation.
