Fewer competing WMs has to be a good thing
Sadly Unity + Gnome3 + Gnome2(forked or otherwise) + KDE + XFCE + the others, is not fewer.
Glad to see someone stimulating some innovation though.
I won’t judge any of them until I’ve tried them all for 1-2 weeks each, and I ignore all rants by people that haven’t tried them. Waiting for Natty release, then I’ll force myself to do a week each of Unity, Gnome3, XFCE and KDE. Still more than happy with Gnome2 though, and will defect to XFCE if I don’t like Gnome3/Unity and Gnome2 gets thrown on the scrapheap.
What is shipped doesn’t matter at all imho (except to those that don’t realise you can have any/all of the desktops with Ubuntu) you just need to install the one(s) you want.
