From one homescreen to another is fluid for me, the idea behind it is that curved Gorilla Glass lets you gesture from the very edge of the phone so maybe they utilized that :)
The big thing is there's glass on the back which conducts heat better than other phones... so it may feel hotter where the processor is during heavy multitasking but... It's all good :D
If you're rooted you have a lot of options :)

Haha! I noticed the dots and thought it was my screen shield, Guess it gives the phone character....
I'mma name them all, this dot can be Wilson... and this one.. can be Wilson.. and.. THIS one... *rambles on for a couple hours*
If you just left an iPhone... I'd recommend that you play with stock for a little bit longer.
As with the Risk vs. Reward... Rooting is SUPER SIMPLE with the Nexus 4 and -> almost <- impossible to mess up
on another note, Bricking a Nexus is also next to impossible...
If you're dead set on...
Don't wait, Try to get a Nexus 4 :3, I'm loving mine nd wouldn't trade it for the world :P
(ProTip) Unless your on Verizon and don't care to switch service.. understandable.. D:
