Yes, but then there's a big difference between Ubuntu (or any Linux or Unix distro; remember, Linux is not Ubuntu) and Windows.
Linux effectively represents an underlying system onto which you put the GUI of your choice, assuming that you want one. I prefer KDE3, but the list goes on, each with their own fans.
With Windows, however, you are stuck with whatever the Beast says you are to have as they insist that the GUI and the system core are the same thing. You can't rip the GUI off and replace it with something else - well, you possibly could, but I doubt that Microsoft would be very happy about that and good luck getting any support!
To be honest, and aside from a couple of niggles regarding Microsoft's almost obsessive concern with security (though after Linus Torvalds' recent paddy about openSUSE's security setup, I suppose I should be a bit careful about this), I don't mind W7 too much, though as with Vista, I am still unimpressed with the memory and disc footprint when compared with XP and W2K. That will probably give you an idea about my thoughts on W8 so far.
What it comes to is that Microsoft are redesigning the front end purely to accommodate the latest fad. This is probably because the previous fad, the netbook, caught them with the pants down, but I'm still not convinced that it has a future. I could be wrong, but the idea of the operating systems that Microsoft bought in were to run general purpose machines, and the touch pad isn't one of those. The obsession over touch and cloud may eventually be their downfall, in fact, since the whole point of the OS moves away from the general purpose system (the standard PC, the monitor, the mouse, the keyboard and such), unless they do something specifically to improve that part of their coverage, there will be a sizeable market that will eventually decide that enough is enough and start looking elsewhere for their services, whether that be Linux, Apple or whatever.
After all, Microsoft ignored their users when they released Vista and Windows ME. Look where that got them!
