Don't need Windows 8? True -- for now...
I belong to a few MS Office blogs, and I remember when Office 2007 rolled out with its Ribbon menu -- a high percentage of users swore at the moment that they would never upgrade from their dear 2003, and committed to send nastygrams to MS to get the old style menus back. What they failed to see is that these kinds of UI overhaul represent a big investment for MS, and history tells you that they will stick to their guns and Will Not bring the old interface back. Windows 9 will undoubtedly attempt to improve on Windows 8, not 7.
What's the issue with that? Using the Office example again, it's been 6 years since 2007 came out, and 2010 has been out for a couple of years as well, but you still have people on the boards asking how the Ribbon works :-\
Don't get me wrong: I'm on the "hate Metro" bandwagon like many of you, and don't have any intention of upgrading any time soon... but I'm also aware that this is where the future of the most popular (or rather, most installed) OS is going, and it behooves all of us to get on the train, like it or not, so we're not trying to figure out what Windows 9 is all about when it comes out in a few years.
