That's a lot more debatable than you think. Vista was crashing all over the place back before they added some patches and service packs, and from a usability standpoint many people despise the new ribbon interface.
The ribbon was yet another dramatic change that was long overdue. Everybody loves it once they 'get it'.
Anyway, the parent post claims windows has got better and you say "no, it was bad now it's been improved" - that's not debatable that's you agreeing.
