Except for XP to Vista...
Except for Vista to 7...
7 to 8... I'll somewhat grant you, but a lot less so after you hit the desktop.

Vista and 7 look very different. The UI was cleaned up a lot, the taskbar was redesigned again, Live Thumbnails and multitouch support were added.
Let's compare that to OS X: most people won't be able to tell Mountain Lion (released 8 months a go) from Leopard (released in 2007), just by looking at the desktop.
Here are two screenshots. One is Mountain Lion, the other is Leopard. See if you can tell which one is which. http://i.imgur.com/VDVPvV2.jpg http://i.imgur.com/0fG7xNu.jpg
Amazing how much they've improved "under-the-hood" while keeping the basic interface the same.
PS. If you can't tell the difference between the two, look at the dock - the only way I could figure it out is spotting the new/changed app icons (Launchpad, iTunes, etc).
Not sure what relevance multitouch has to the appearance of the UI.
That's like saying that there's almost no difference between XP and 7, mere polishing, because of http://i.imgur.com/yZcifMF.jpg vs http://i.imgur.com/Z4TqGSV.png
Vista and XP looked pretty close. The real difference was the Gadgets: http://i.imgur.com/kYt9Xqm.jpg which can be turned off (and if that's a big difference, well, "Mission Control" and "Launchpad" mean a big difference for OS X).
