CNN has an article about Windows 7 up, which MS promises will be in early beta in 2009 and for sale in 2010. This feels like the 98-Me cycle all over again: release a version of Windows that has more bugs than a rotting corpse and almost immediately thereafter release another that fixes a lot of those bugs but does little else.
If this is actually released in 2010, I can't imagine anyone having an incentive to upgrade an existing computer system to Vista now.
