Thanks for the input. I'm a bit apprehensive about rooting as I've never done it before. But I googled CleanRom and came across this:
How to flash CleanROM Inheritance ROM for the Transformer Pad Infinity TF700T
It seems very simple. Is this the way you did it?
Understable, that you are apprehensive! And a good place to start from! It's most often the gung-ho, devil-may-care type of user who makes mistakes and screws things up!
First: Get the tablet and then - IF you are unhappy with it's performance - start reading here:

You'll probably have to read it more than once until you understand the process. Proceed only if you are confident you understand the necessary steps.
If you are unsure, ask on this or another forum before you do anything half-baked.
The guide you linked to is not bad, but describes the easy part of the flashing process and the version numbers of firmware and custom roms are outdated.
As a rough overview (the single steps are described well on the XDA forum):
You have to unlock the bootloader using the Asus Unlock tool. Unlocking will void your warranty.
You have to install a custom recovery like TWRP or ClockworkMod on your tablet.
Using the custom recovery you can flash custom roms to your tablet.
TBolt recently wrote up a pretty good summary of the process. I'll try to find it and add it as an edit later.
