With the launch of the New iPad you will have noticed that to take advantage of (it's frankly amazing) Retina display it's apps are ballooning in size at an alarming rate which means that your 16GB iPad will be full in no time if you are anything like me! Even with my old 64GB iPad by the time I had a decent music library loaded on and a few movies to watch whilst away it was getting close to capacity.
My Transformer Prime now has 196GB of storage in side it's sleek, brushed aluminium chassis (32GB std, 32GB MicroSD in the tablet itself and a 128GB Lexar professional SDXC card in the Dock.)
That should see me good for a few months at least!
