That's VERY short for a netbook. AMD's X2 is a powerhog compared to an Atom and this new psuedo netbook (AMD does not have a true Atom-like low power CPU yet), gets 4 hours in Windows 7 with the standard battery 3 cell battery:I think the 9.10 remix has a better power management scheme. Especially if you turn the always on fan to auto. I get a solid hour or so of heavy usage with the stock battery. A guy here has the EEEPC with the HUGE battery and he goes about 4 hours.
<edit> An hour is more than I ever got out of my Powerbook or my Thinkpad, so I'm happy with that.
