Leo got the new iPad Air 2 (in opulent Gold, nonetheless) and he says while it's nice and has some new features, you don't really need it. Save your money. Tablets are so mature these days that there really isn't a benefit from cashing in your old one and getting the new one. The only real benefit is that the SIM can be used for almost any carrier, so you can switch carriers on the fly. Other than that, there's no real need to buy a new one.
