So are you actually saying that Vista is faster than XP on the same machine? That's not my experience, though Vista isn't considerably slower.
I agree that OS X and Windows are fairly similar in design though but making it different is certainly disadvantageous to Apple as it makes switching more difficult.
If MS get a new OS in 3 years I doubt it'll be a big improvement over Vista.
On the same machine, Vista feels quicker, I don't know if I could scientifically conclude that it is, if I tested it rigorously XP would probably be quicker, but then again XP doesn't have Aero and other extras which are nice to the User experience haha.
The thought that both OS's are similar to allow more consumer adaptation is great, never though of it that way, but it does make sense that they will continue to be pretty close.
It also looks like MS's new OS isn't going to be what they are concentrating on so it sadly will be just ok and not "Wow". With all their new technological et ceteras like seadragon and the big ole' coffee table it's easy to see the Microsoft 7 being just like Vista, but something companies and colleges/ect will adopt quicker aka Vista the way it should've been done.
and ole davey pogue, sad I can't watch youtube in Thailand
