Neo900
From the people who made the GTA04 (the 3G successor to Openmoko's Freerunner) here is an idea to revive the best in the N900: http://neo900.org
(TLDR: motherboard replacement running Linux for the N900 case)
Starting tomorrow a partial prototype can be seen at http://ohsw.org/ (In Garching, Munich)
ATM they are waiting for 17 more (for a total of 200) 100€ down preorders to continue to production.
