is N900 service port (which is usb-compatible) separate from N900 micro-usb port?
also since you estel done hdmi out mod (one with raspberry pi) is it enough place in "fat" cover to enclose ethernet-enabled version of raspberry pi?
also you seems to say that mounting is in price, so maybe I want too send several n900s for modding in one package (to be sent back after modding). I want to spread some N900s at my friends (not for free of course), so maybe they would be more interested in modded ones (as unique is great keyword for catch-up).
offtopic question: does N900 screen part is costful? how hard to replace those? I ask because some N900 I ordered as used hardware is very scratched. can be sratches fixed without replacing whole screen part?
