512MB would allow to move some currently optified libs (e.g. qt) to NAND wchich would be great... 1GB stated on n900.org would be a dream as even more stuff could be deoptified. Obviously the more the better, e.g. 4GB (probably impossible keeping the price reasonable or due to technical reasons?) would a) gives us ability to forget about /opt on EMMC in Fremantle and move its contents fully to NAND (which has its downsides - /home on NAND could damage it after few years of usage); b) would allow flashing of bigger linux distributions (backtrack fully in NAND, anyone?). I for example would want 1GB or more, but I could accept 512MB without nagging. If it was even more, I would be happy as a little girl
