Looking to improve my awareness of network operations and pen testing. I've made use of BackTrack and Kali in the past and having it more portable than even a laptop is very attractive.

I've read a bit on the Galaxy Note 10.1 being able to run Kali... and then I came across NetHunter.
I was wondering for those who have used either what your thoughts on the Pros/Cons are for Galaxy Note 10.1 w/ Kali, Nethunter on a Nexus 10, and Nethunter on a Nexus 7.

Also are there any other notable options that I should be considering?

A bit is a simple and generic question but since i don't have a tablet yet and would be getting it for this purpose, your suggestions will be appreciated!
