The only extra daemon that should be running (apart from the standard fare that comes with the os) is the ssh server, and I doubt it's draining too much battery. I think wifi is to blame (as I said, I use it for browsing, rss and email, so the wifi is constantly in use).

No, power saving is active.
I'm trying now without claws and the corresponding ssh tunnel (i.e. just the browser) to see if it lasts longer (though the battery applet is flip-flopping constantly between "2 hours left" and "1 hour left").
edit: anyway power saving only works when there'ss nothing to transfer, in another thread I explained how wifi sucks around 50% cpu when wgetting a file.

Ok, after 2 and a half hour of just browsing I see the low battery alarm. I should have enough juice to post this...

I've seen the 2 hours battery time in two scenarios only:
I've seen the 2 hours battery time in two scenarios only:
- When listening on streaming internet radio. This _sucks_ power.
- While using one particular SiS chipset-based wi-fi router that I own, it somehow manages to disable the N800 wi-fi power saving function. I own other (newer, faster) wi-fi routers as well, and none of them (or any other I've used, for that matter) exhibits the same anomalous behaviour.

Funny she (or "he" according to texrat, edit: now I see that it's actually signed by Matthew Stevens) complains about the 2 hours battery time of the thinkpad, since I don't get that much time out of my n800 (maybe the n810 has better power management/a bigger capacity battery).
Oh, and I don't get even an hour out of my thinkpad, so the tablet is definitely better wrt battery life.
Now, if I could only figure out how to get Dicewars to work offline...

Another short battery life scenario is a cheap wifi router at my in-laws; I kept losing connection until I saw in another thread to bump the Power Saving mode to "Intermediate." This solved the disconnection problem, but, as I was warned when I changed the setting (under Advanced / Other on the connection setup box), "Changing to this value increases power consumption significantly." ... Wow, the battery just seems to evaporate at their house.
