What are people's experience of actual battery time?
I seem to be getting less than 3.5hours having done nothing more than play some games and look at various pre-installed applications, with wifi turned off, and am getting more like 2-2.5hrs I think. My EEE is just over a week old.
Have I got a faulty battery, or does this figure refer to some ideal use that I am never gonna actually achieve? Or does the battery need more time to bed in?

Playing games, depending on which ones, can consume a lot of CPU - so your experience seems about normal. I think the 3.5 hours is maybe with 1) no CPU consumption, 2) no wifi, 3) no sound, 4) low screen brightness.
Manufacturer's always overstate actual battery time, welcome to the real world.

My experience is around 2.5h with light use (but almost no screen-off time!).
EDIT: I've pre-ordered the bigger battery. 
Clove.co.uk says it'll be March most likely.

Depends what I'm doing - 2½ (wireless active) - 4 hours (wireless not active, brightness low)...

my tests on the road with wifi off, speakers off, webcam disabled and brightness ~60% gave me between 3 and 4 hours runtime, depending on what i was doing...

That's cool that you can eke out 4 hours in a pinch.
I'm thinking that these batteries will all need a few charge/discharge cycles to get up to full performance, right? Maybe a lot of Eees are too new to really go by.
Mine should arrive tomorrow, I'll try to keep track of my battery life too.

Same here. no wifi (no internet), no sound, no cam, writing in kosole (nano), average brightness... about four hours,
Games may be the reason in your case, I think.

I get between 2 1/2 to 4 hours of battery life (down to 20 %) depending on what processes are running. I don't do any heavy gaming, no camera, no video, so very light usage of the cpu.

I can get between 4 and 4 1/2 hours out of a charge (down to 20%) if I am just writing. That's with wireless disabled, and screen brightness turned down to 50 or 60 % (which is as low as my old eyes can cope with).
In more general use, like playing games, using the internet, etc. (but with the screen still turned down), between 3 and 3 1/2 hours is more usual.

When I say games, this is mostly if not quite exclusively Frozen Bubbles, which I would imagine to not be too demanding...

2.5 to 4 hrs depending.
frozen bubbles certainly is pointless fun.
(home sick today, so glad I have my eee to keep me company)

With Ubuntu 7.10 and the internal Sprint card in place of the modem I get 2 hours and 5 minutes. Can't wait for the 6 cell batteries to come out!! Or 8 cell :X

Turning off wifi and turning down the brightness give you quite a bit more run time vs full brightness and wifi always on. I don't have any hard numbers unfortunately.

Well, I just received my Eee last night, and after a full charge over night I found that I got roughly 3-3.5 hours out of the battery. This included mostly word processing, some light WiFi use (had the WiFi off when not online), and playing around with the "games" preinstalled on Xandros. I also had the screen brighness around 70% and the volume turned off. Overall, I was very pelased with the Eee's performance.

notebookreview.com says
After two hours and 8 minutes of browsing the web wirelessly and watching a DivX movie the low battery warning popped up on screen and reported that the Eee PC would shut down in 3 minutes unless it was plugged into a power source. The Eee PC then kept working for another one hour and 15 minutes before the notebook shutdown. Bottom line, the on-screen battery indicator cannot be trusted.

^^ After about eight charge cycles (since switching to Ubuntu 7.10), the Gnome battery applet is still "learning" the Eee -- it still short counts the available battery time. I noted that it was slowly getting more accurate as I used the Eee with the wifi off and the screen brightness down to watch videos on planes (looked like north of three hours in this configuration).
