This Asus Eee PC 904HA comes with 6-Cell Battery Pack and 160GIG harddrive. It is based on Intel Atom N270 1.6GHz CPU and should be as fast as my Eee PC 904HA. 160 Gig HDD is a very nice option. Battery life could be as good 5 or may be even 6 hours. One difference between Eee PC 904HA and Eee PC 901-904HA is slightly bigger.
