my opinion:
neither maybe the psp if you plan to game a lot. I was about to sell my n800 with the intention of getting a netbook instead. Fortunately a friend gave me a msi wind and an eee to set-up for him. Hmmm, horible little machines. Hot case, small battery, bad keyboard, useless trackpad. It was good for me - I rediscovered all that I love about the n800.
