New firmware upgrade is available for zen6 WW

Hi all,

I'm still waiting my zenfone 6 on it's way, according to the website that i buy it shows Z2580 2.0GHZ atom. imported set.
still very afraid they gimme the Z2560 version!
very exciting of it!
a few question to all sifus.
by the way I'm almost long time iOS user since 4.0 before that i'd used symbian s60
rarely touch on android stuff. eventhough i'm a developer.(very paiseh)
1: should i root it?
2: should i update to 4.4 kitkat or stick with existing JB?
if yes for q2 ->3: what's the main reason to update 4.4?
if no  for q2 -> 3: what's the main reason i should update?
4: if i have any .apk files i can straight away install it into that phone by transfering to my microSD?
5: will the ZenUI caused troublesome?
6: is there any possibility to have split windows features?
7: I'm a sales person so what apps that whould be recommended for productivity use?
8: is there a very big different between the 600CG and 601CG for zenfone6 i mean interm of performance, daily usage, battery life and so on, I'm googling but still haven't found any review for the both comparison.

thanks a lot in advance!!!

Tried, looks fine to me

And i think i know why my memory card slot kaput

It always happen when after play games, the phone heats up, probably damage the slot

Pricing sure do have different ady. Looking on current zenfone mainly is budget and 2 gb ram affordable smartphone
