nice... I'm still using my old 10" with a single core 1.6GHz atom of the
first generation. Processing power almost like at the start of the
century (A 1GHz PIII has more punch than this thing!)

I've been using dt on my 1024x768 screen. It's almost usable. Or: it has
been, until ubuntu managed to break the wm so I always have the UI only
partwise on the screen :-(

Oh... good to know. But does it also have an impact on the result? And
if yes, how much?

Would be nice for the few atom powered devices out here. But since I
think that the atom was a stupid design to start with that will
hopefully only survive in some tablets (if we are lucky, it won't show
up there too much as well) and is not really suited for any kind of
serious work... I'm not sure if it makes sense to put work into
something like this (remember, I'm in the same boat but I consider it
only a real last resort and try to avoid dt on this thing).

Sure, if someone is willing to put effort into this I'd be happy to have
dt a bit more workable on my netbook... but I'll never blame someone if
there is no such support because dt on a netbook seems like a real
corner case for me.
