It seems to be pretty accurately reporting the true capacity. It died, or at least went into suspend mode, with about 10 minutes remaining on the meter. On a fresh battery it reported about 4.5 hours available, and I used it for at least 4 hours continuously, with wireless enabled and the screen up all the way. If I turn the wireless off and the brightness down it goes up to a shade under 6 hours, but it's more difficult to use the internet in the middle of a field like that

Under XP it normally reported around 3 and a bit hours, up to a little over 4 with no wireless and the brightness down all the way, and I would usually get about 85% of that in practice before it hibernated.

One thing it might be, I suppose, is different memory usage patterns. Ram is a real power hog and perhaps XP fiddles around in memory more than 2000? Or possibly the intel speedstep dynamic clock management is more efficient on 2000 with the separate application than the built-in one on XP. I'm not sure what the difference is caused by, but it seems to be real.
