Why do you assume that X is overhead that needs more weight and  
battery capacity?
X11 is also using the same framebuffer as others are using. It is  
just a different software

The phone functionality (GSM) of the Neo comes from a separate  
module. So, adding
one to the N800 wouldn't change anything in the performance of the  

BTW just for the record, the first Linux wristwatch from IBM did also  
use X11...

IMHO it is a common misconception that X11 raises performance  
problems. It is
mostly how X11 is used. E.g. if you flush too often, performance goes  
down because
it cannot combine and buffer screen updates any more.

BTW: some of my experiments indicate that the framebuffer itself is  
the slowest part
in the game.
