why was this discussion thrown in cold. Or everyone is on the same
plane except me. Or
Openmoko has already decided and its set in stone. I still believe
using 6410 in GTA04 is nothing less a disaster than usage of glamo in
GTA02. Please have a good discussion on it in your team before you go
ahead with Samsung.
