PS the battery lasts around 5 hours with normal usage. Don't believe the mfr's battery ratings, cut them by 25% and you might get a reasonable estimate of how long they will last under normal usage.
While that may be true with normal usage, I consistently get 6+ hours out of my 1000H. You just have to be conservative. That is 6+ hours surfing the web with some video. You just have to keep it in power save mode (which changes the clock speed of the processor) and keep the brightness at the lowest level you can comfortably use it at, for me that is one click away from the lowest lvl. Also make sure bluetooth is off if you are not using it. If i turn off the wireless card as well, which you can do at the push of a button, I have stretched it even a bit further just doing things like word processing and excel. But if you watch a lot of video and keep the processor speed up higher, yeah you can excpect 4-5 hours. But still, try doing that on a full sized laptop.
