Currently I own Wfi only iPad Air, while I love it, I'm desperately in need of more space. I thought 64gb would cut it, now almost every 3 months or so, I need to restore completely to free up spaces as much as possible. The way I see it, it's almost unusable without wifi connection. So I looked up what I can do, and one of the choices I have is to buy a 128 gb refurbished iPad air 2, and sell my iPad. At any rate, I think it would cost me around $400 or thereabout in total. I guess the real question is: is it worth it? or should I just wait for iPad air 3 instead?
