I might be able to wait for the iPad Air 3, but my iPad 2 is increasingly ticking me off because of it's performance. I'm leaning towards an iPad Air 2 at this point, since the processor is so much more powerful than the Air 1. But I'm looking for any convincing arguments to sway me in another way.
From a marketing standpoint, the Air 2 is more powerful than the Air 1. From a real world perspective, you'll have to look hard to spot the difference in performance. The main advantage the Air 2 has besides Touch ID is 2 GB of ram.
I own the original Air and purchased an Air 2 and it was really hard to tell them apart performance wise. I think as someone else suggested, waiting for the Air 3 is the best advice or buying a refurbed Air 2 from Apple when Apple starts selling them.
I'm going to have enough money saved up in June to replace my good ol' iPad 2. I do some gaming, web browsing, music streaming, the normal stuff, on my iPad currently. iPad Air, or iPad Air 2?
Wait for the iPad Air 3 and hope for the best. I just got the iPad Air 2 and am having fits with the 'touch' issues on the screen. They just don't work right. It makes it almost unworkable. If Apple doesn't see this serious problem as important then the next iPad Air won't be any better.
