So really - what you're all sating is quite simple.
They should have stayed with windows 3.11
or stayed with windows 95
or even windows 98
maybe XP should never have been invented
or even windows 2000 or indeed before that.
Seems vista was a mistake - but based on your above theory they would never have created windows 7
But Martin - remember this, they are not forcing you to use thier softwarem they are meerly giving you choices.

I personaly never tush into a new OS.
Never wanted to stray from DOS games, my mate forced me into trying win 3.11, was ok. he then got me to try win 95, with this I suffered my first ever virus.
Went on to win98, also tried millenium, quite like the way it could be tweaked into doing a superfast defrag, sad really.
Eventually moved on to XP Pro and still am using it.
Never bothered with Vista allthough I did recently purchase a laptop off a member due to an upgrade and it has vista, had a quik look but thats about it.
Personally without microsoft "Changeing things" I didnt know what I wanted till they upgraded it for me.
