I love my netbook though.
That's weird. I have the same thing (U100, 6-Cell 4400 mAh battery). I can get at least 4 hours (almost 5, usually) out of the battery. This is with the lowest brightness and only Wi-Fi being on. Light web browsing, maybe a bit of word processing. (This was with Windows 7, which seems to be just as good on the battery, if not better, than XP...also, I always had aero on)
Do you have OS X installed, by chance? If so, that will definitely decrease your battery life. You may not, but if so, try this:
1) Upgrade to 10.5.7 (it really helps)
2) Buy Coolbook or install the VoodooPower kext (less stable, but works fine for me) to enable speedstepping in OS X (originally disabled, causing higher CPU power draw when unneeded)
