I have heard nobody say this is the reason there is no Maemo 6. Also, a repartition of the internal space (considering it comes with a 32gb internal card) would negate this. It might run slower, we won't know till it's there.

So, if they were interested in supporting it, then they simply wouldn't release it in an SSU fashion. They would release it as a complete reflash, which is perfectly acceptable.

And UI input differences I just don't see it.. they can't possibly make such heavy use of multi-touch that it renders the UI unusable without it. That would just be insane.. I mean the phone CURRENTLY is hard enough to use with one hand - if nearly every gesture, including clicking a menu button, required two hands and multiple touches... that would just be sad.
