I think everyone has, between them, said what I'd say.
For me the size settles it. Either the size of the Note 3 is a big plus or a big minus, but either way it's a big enough difference that for me it would settle it one way or another without considering anything else.
TBH I am of the opinion that if Android reaches the point where you *need* 3GB in 2 years' time then the platform has been lost to bloat and I'll be looking at the alternatives. There are actually very few 2GB phones now, so if that's not enough you'd be arguing that the Note 3 will be the *only* current(ish) android that will be usable 2 years from now, including Nexus devices and Samsung's own S4. I don't buy it myself.
