I agree, GNOME is too heavy for the XO, no matter how much you pare it
down.  I think we need to make sure we aren't headed for disaster, where
people's XO's are bricked after a few months because their SD cards
reach the write limit (due to heavy swapping), and go belly-up.

Even if the SD card can last long enough with swap and GNOME, I think it
may *still* prove unusable.  And if it turns out a swapfile on the SD
isn't doable, GNOME is a non-starter.

At least XFCE can run a bit better, possibly without swap, or at least
swap less (which would help the SD card last longer).

We're asking a lot of the XO to run a modern desktop and modern apps, we
should be prepared to throw quite a bit of functionality out the window
just to get it to run at all.
