Now, the question is why is that a good excuse for the G1, while there is a chance that will be exactly the same (speculative) reason the N900 is not getting Maemo 6 ? Or will people suddenly say 'ah ok, flash space, then I'm cool with the N900 not being upgraded' ? There are three things that can kill Maemo 6 on the N900 - NAND/opt/flash space, RAM size and input UI differences. While you can go and argue about UI, RAM and flash size are a given, and there is no point of M6 on the N900 if it sucks because of these two. It would be even worse than the current situation to say 'hey fellas, don't worry, you'll have M6 on N900 !', only for the users to discover after an upgrade from M5 that it works like Vista on an early eeePC.
