I am, although being Gnome 3 based it won't be the snappy experience one would expect. I can understand their choice though: having to liberate a tablet recently (Asus T101) I tried at first to use XFCE as I do on all my other hardware, but though it ran really fast that was a usability nightmare: absolutely no way to have a reliable screen rotation and trackpad management without patching here and editing there with the risk that it would lose the functionality at the first upgrade. I also tried lxde, mate and other light desktops with results from bad to very bad (wrt screen rotation, all hardware except camera runs fine) then just before giving up I threw Gnome3 at it which worked immediately, but it's definitely a resource hog.
It's "GNOME 3 based" in that they're working within the GNOME project and using their apps, but it doesn't use GNOME-Shell which is the resource-hog part of GNOME 3.
