OK, so here's my day with my N900.

Email updates every 30mins, 15mins rss updates, connected to gtalk and skype all day and weather updates every hour.

Unplugged N900 at 8.30am,
idle till about 10.30am, then browsed a little and tried to downloaded a 175mb which crashed.

Took photo, checked phone and email/rss every now and then.till 1pm.

Downloaded 175mb file at around 1pm, then kept checking email/rss/phone every half an hour or so till about 6pm.

Then got a call around 6.45 for about 10mins, then two/three more calls till 9.30pm.

And also browsed the web for about 20mins relisting an ebay item.

Now down to 11% according to lshal - but lshal only reports upto 94%.

Should last me till 12am before starts saying low battery.
