Yes, I read that one already, thanks anyway though. I remember also looking at the comments, seems like quite a few had problems so I'm a bit hesitant to try for myself heh.
Incidentally, I'm writing this message from my tablet and it appears that the keyboard runs much smoother and is easier to navigate on JB 4.1.1. than on the Ice Cream Sandwich version. I also remember now having touchwiz errors on ICS. There certainly are more pros and cons for each OS than I previously thought of.
I like the idea of a clean (rooted) device where I can remove a lot of bloatware, but on the other hand, with officially released firmware you'll usually get the benefit of an operating system that's been tested over a longer period of time, a system that works out of the box. I really don't know what to do right now so will wait and see. :/
