I just have to say that I love seeing threads like this. I'm in total nerd envy. Its fantastic that you guys are really modding your devices - inside and out! Kudos.
I took the back off the Nook and disconnected the battery.
I removed the tape on the battery on three sides
I drilled a hole.
I chamfered the inside edges
I glued a round 1/4-20 T nut in the hole using JB Weld epoxy.
I used a bolt and an old plastic lid with a hole in it to pull it tight for drying.
I reassembled the Nook.
The next morning I removed the bolt.
Now I have a Nook that mounts on those little bendy camera tripods.
I can also just stick in a 1/4-20 2.5" bolt as a leg.
I'm going to get an accessory arm so that I can put it on my mic stand.
When I bought the stand it was $8 US.
The price seems to have creeped up to $12 in only a week. http://www.amazon.com/dp/B002PAW6EG/
The photo shows the wrong length gooseneck, mine is 8", 20 cm long.
Besides reading books, I use my Nook for display of my guitar transcriptions with lyrics and for recording 24 bit audio.
I don't use a builtin mic, I use a Shure SM58 (standard stage mic) and a Lexicon Alpha USB interface.
Getting it to work is all part of this thread: http://xdaforums.com/showthread.php?t=1457971
I haven't really ported my guitar transcription display program over to Android yet as it's actually quite complicated.
I format songs as PNGs on my desktop and then have a simple program on the Nook that can scroll them.
I have a database front-end for looking up songs that's actually more convenient than anything that I have on my desktop.
