Anyone here have any experience of writing a script on a netbook?

What I'm chiefly interested in is a) the ability to install software (can you put a screenwriting program onto a netbook?), and b) the keyboard size (how comfortable is it?).

I write on a little HP mini all the time when I'm out and about or over with the band... Sometimes a screenplay - Sometimes lyrics or chord arrangements.  But, yeah, I believe it's functional.

& Just because there is no physical media drive, doesn't mean anything.  I have Windows 7 installed on a 8 gb mem stick.  I have Sophocles, Movie Outline, Final Draft 8 and Writers Café' installed on that mini HP too.  If you know what you're doing it's very easy to extract and make bootable applications from physical media.
