Re: Vista wasn't that bad in retrospect.
Vista's biggest problem was the longevity of XP.
Up to and prior to XP, Microsoft's stance was:
Upgrading Windows? Then you needed upgrade your old computer, or get a new one, and be ready to get all new peripherals, 'cause the new Windows don't play nice with old stuff.
Then XP came and stayed, and stayed, and stayed.
Computer's got faster and more powerful, peripherals evolved ever more complexity, No problem, XP chugged right along. like it had for years.
Then Came Vista, with the same "obsolete everything" paradigm of old, but times had changed. People were used to everything working with Windows, no matter how old or new, and PCs were competing with phones and tablets that 'just worked' out of the box.
As further salt in the wound, In order to push Vista, Microsoft allowed retailers to slap it on 'Vista ready' systems that could barely run Vista, let alone any useful software with it.
That one-two punch killed Vista, and left a dazed Microsoft looking around and noticing for the first time that they no longer had everything their way.
