I recently purchased the Asus EEE 904HA and am in love with this computer and would suggest checking into it if the Mini 9 is what you are looking for. Newegg has my current model for $349, though I ended up paying about $240 due to mirosoft live search and a free upgrade from the EEE 900HA. This computer is more along the lines of a regular laptop IMO because it weighs about 3 lbs, has a 160gb HDD, and Windows XP. The battery lasts about 6.5 hours, the speed isn't an issue since I bought it for the specific purpose of being a low powered notebook and it is fine for the internet, movies, music, and wordprocessing.

The one real benefit of going with the EEE 900HA or 904HA is the harddrive which makes storage a non issue, Windows XP comes standard(home fits my needs on this computer), and there is no tax outside of CA or NY. Currently Dell has the base Mini 9 selling for $350 with a 4gb SSD and 512 ram, unless you are getting one for a deal with a Dell laptop, skip it and go with one of the Asus EEEs
