Most tablets have a far too small internal memory and no way to move them to the SC card unless you root it
Tho' not directly relevant, I have the same problem with a netbook computer, an ASUS EeePC, which only came with 1 GB of RAM - maybe why it was such a 'bargain' to buy !!. but it is unbelievably slow as a result of the programmes I have installed, and would like to keep.
My IT man purchased an extra RAM chip for me, but then found that it wasn't a simple Plug 'n Play exercise, but a major motherboard rebuild - which he wouldn't do, and ASUS have confirmed that it is impossible to upgrade this model with extra memory.
However - there is a slot for an SD card, so could I improve my situation in the same way that has been suggested to 'vulcanised' above ? I also have 2 USB slots available.
