Do not buy an ICS tablet if you want JB. It's that simple. You are never sure if the maker will issue that update.
There is no reason to repeat what others have learned about this.
As one of many being totally confused as to which Tablet to buy, after all the usual attempts to eliminate potential "bombs", the one question I have been unable to have answered, properly is when looking at machines available how do you know if it will have an up-grade from ICS to JB. What has further confused me is just one hour ago reading a punter,s review of a Samsung machine with ICS and he was able to up-grade to JB himself using Kies.
So, before buying a particular machine which only carries ICS, how can you tell if an up-grade is possible?
