Performance work has now started for N900/DE images, biggest problem
is the memory foot print. N900 has 256 mb of ram and at the moment it's basically the amount of mem we have already used once the device has booted up. (Which takes about 70 second atm.)
Current images includes btw also the gpe-mini-browser in addition of fennec.
It's much lighter (about 10 sec startup) while still providing good rendering on pages I have visited.
