I'm currently typing on an EeePC 900HD, the slightly newer Intel model. But my older one (same model, now dead) had an Atom processor, and it did perfectly well with Open Office. For a while it was my only Windows box, and I used it for most of my Youtube and Netflix streaming.

Also, just beware its maximum video card resolution is ~1024x768 for a standard aspect ratio monitor, but I've had it connected to a 1080i TV, running as 720p with no problems whatsoever.

OK, some videos were a hair demanding on things (considering shared graphics processing and ram).

For a bit between more permanent places to live, I was using the TV setup (with wireless keyboard and mouse) for streaming videos, general web surfing, creating documents with Open Office, Skype, and even photo editing (a hobby).

Some things may take a minute to load, and I recommend upgrading your ram to max, but a netbook should do you fine.
