Where can I find an accessible and complete description or layout of the N800 hardware components? For example, what is the 1mm opening on the top edge, center?

go here and watch the video: http://tabletschool.blogspot.com/200...bout-n800.html

edit: by the way, that opening on the top is the microphone

Yes, thanks, I've seen that video (which doesn't mention the microphone) in my searches, but I'm looking for a more complete reference, something simple in format -- like a series of pdf-file diagrams with descriptions and, ideally, specs.

I searched Nokia's site under the assumption that it offers a better resource that's available some place, one that fully describes the device (that is better than an amateur's well-intentioned, but fluffy [superficial] video), but perhaps they haven't bothered.

Thanks again.

wikipedia has specs. http://en.wikipedia.org/wiki/Nokia_N800
