Lol.
The software on mine has become laggy. Its mostly my fault for having 3 dozens of resource heavy apps that I don't use.

And its more my fault for staying on a TouchWizz base... simply because of MOD'ed Multi-Window feature.

I think I will upgrade my OG to #3 instead of #2 because:
- community support from N1 and N2 will jump to N3
- samsung support N3 > N2
- the usual upgrades are welcomed (screen, soc, thin)
- the new dimensions are great, not perfect
- symmetrical pen is nifty
- new software features are nifty
- USB 3.0 could be useful, at least for charging
it might come in handy with my Gold-plated expensive microUSB cable and 2.1A fast-charger
- improvements for battery life (more efficient code, soc, radios)
- its new, come on

Disappointments I found:
- bezel could be shaved even further (Samsung you doing this on purpose aren't you?)
- speakers... they suck. Need HTC One tier for a phone of this calibre
- kickstand
- nothing really exciting (OtherHalf, Detachable qwerty, Detachable SHIELD-gamepad, Laserpointer, Buttscratcher etc etc)

...Does anyone know what the best way is to get an Unlocked version to Australia with the Snapdragon 800 chip? (I don't need the Exynos' power, but the QSD's extra battery life is going to be handy)
