I'm not saying Windows should become OS X. It already exists, it's called OS X :)

OS X is not perfect and there are an infinity of good ways to do things and an even larger infinity of bad ways. By comparing Vista to OS X I was not implying that it should become OS X, I was just pointing out why I feel Vista is inferior in some of it's basic GUI elements.

Operating systems can and do change dramatically. Look at the quantum leap forward between Win3.1 and Win95, that was a big change, a real paradigm shift, but people got on with things and enjoyed the new OS. The way MS are hyping up Vista you'd expect a similar quantum leap forward but it's just not there. This was their big Windows re-write, they can't do that again for many more years so we will be stuck with derivations of this for years to come. They had a chance to make a leap forward and didn't take it.

I've kept my examples MS in this reply to keep to the 90% audience but OS 9 to OS X was one hell of a jump even though it was only for the 5% out there who used Mac and that too went very well. You can make big changes and I think MS should have.
