No. My 3rd gen iPad is able to do whatever I want on it. I don't see a reason why to buy the iPad 5, given that the OS doesn't allow me to multi-task or to do things more powerful. If Apple doesn't make the iPad more of a power tool, I'm moving away from it. I'm either buying a Windows tablet or not buying no other tablet at all.
Going from 2 to 5, hopefully future-proofing with the 128 GB version.
