One reviewer here in the Washington DC era wondered if Vista is really the last big PC-centric effort from Microsoft, in a world where both applications and "operating system" are moving to new models.

I don't know, but I sure am glad that for now at least I'm not forced to upgrade.

That same review used a phrase I'd forgotten: "boil the ocean," referring to giant software efforts that try to fix everything. Probably explains a good part of the delay between the last XP and Vista.
