"I think Microsoft's business model is eventually doomed, but not in any time frame short enough to make the Yahoo deal matter in that regard" I'm not so sure

"I think Microsoft's business model is eventually doomed, but not in any time frame short enough to make the Yahoo deal matter in that regard" I'm not so sure about "doomed" -- "threatened," I might allow, for a sufficiently liberal definition of "eventually." Vista isn't doomed because the desktop is dead -- it's doomed because it sucks. Web software may represent a legitimate threat to Microsoft someday, but it seems the more immediate concern ought to be that they can barely develop software anymore. It took 6 years to get from Windows 95/NT to Windows XP -- a huge step forward in so many ways. Then 6 years later, Vista brought us what, exactly? Worse performance on the same hardware? A pretty new interface that practically requires a 3D graphics card to open the start menu? DRM? A completely reorganized interface offering negligible improvements over the old one? A privilege escalation implementation that causes as many problems as it solves? An eye-popping $319.95 price tag for the "full" version? Sign me up...
