Yeah, I wouldn't go this route either - the Atom processors are really fine for office and can cope with 2D art aps just fine but they would struggle with rendering. Their strength seems be in lowish power consumption, so even my cheapie netbook can manage just over 6 hrs use typing and watching films etc.

Having said that, I did figure that my netbook specs were actually better than the machine I started using Poser 4 on (a lot better, in fact), so I tried out Poser 5 for fun (I could try some later versions but can't be bothered). I keep it there with a selection of toon, Nursoda, and Smay figures to create quick illustrations for emails and such (a bit of fun or the family). So, they aren't a complete loss for Poser users.
