whats the most battery-sucking activity that one could do on the N800? i'm guessing SKYPE (drains my battery from full to empty after 30 minutes)

ok
I want to run skype for 3 hours. That means I want to be able to actively search the web and go to energy-hungry sites for 8+ hours. I want to be able to listen to my music on Canola for 15+ hours straight (screen inactive). I want to be able to watch video on MPlayer for 6+ hours

i'm asking for a lot, but i'm sure theres somtehing... and you get what you pay for, right?

seriouosly thats one of the most disappointing parts of my N800.. its battery blows compared to the Touch's
