This device uses Maemo 5 software on Linux.

This sentence gave me shivers. I know its nothing new, since the 770, n800, n810, Google Android etc all run on linux, but to see it in writing in a manual, on a device as open as the n900 by a major company like Nokia bodes well for the future of Linux and Open Source Software.
(Should the word "Based" be put before the on though? The sentence structure seems odd)
