I'm hard of hearing in noisy environments, so my application idea is a "smart hearing aid/music player/noise canceling ear phones", ie. I want to be running the thing continuously, with the lid closed, in my pocket, with (at least two channel preferably more) microphone input and two channel audio out.
1) Can it run with the lid closed? 2) How long will the battery last on one charge?

I have measured about 5 and a half hour runtime with the display turned on and the cpu decoding ogg vorbis audio files. You can expect it to run some more hours when you turn off the display backlight (which you won't need anyway when you close the lid).
With only cron running (I was testing maximal battery time) it was running from 1 am to 6 pm, more or less. Around 15 hours, but without processing anything or the like, also the screen was off (it auto turns off after a while) and the lid closed.
