Just posted a link in the laptop / netbook forum for a Dell Mini 9
special through tomorrow. $249.00
Notebookreview.com has pretty thorough reviews of most netbook models out there. I included the link to the mini 9 review.
You can compare the units yourself using their site.
Acer Aspire one
Dell Mini 9
Asus Eee PC
I'm rather fond of my Aspire One. it does OK for the specs, most of the netbooks are similar low spec machines..
I did like the Lenovo S10 with access panels to get to all the important bits for upgrading Memory, wireless, etc.. but the deal I found on the Aspire one at the time was too good to pass up.
the nVidia ION
platform looks promising. A GOOD GPU in a netbook.. but those weren't around when I bought mine.
Probably in the higher price range though.
