My current 128GB 4 'full house' goes everywhere with me but I am noticing it often slows on processing specific tasks and at times it's a hefty wee lump slung in my carry-all.
I like the large size screen of the 4 but I really would love some input if there will be an advantage that's noticeable thanks to the A8X chip in the Air 2. Of course I'll be going for the fullest spec'd 128GB Air 2 4G, etc....
Hello - I cannot comment of going from the Air to the Air 2, but I did transition from the iPad 2 to the Air 2 and have enjoyed the many changes - as to the Air, for a comparison, take a look
HERE which makes a strong point for obtaining the Air 2. Of all of the features listed there, the downsizing in thickness & weight and the Touch ID have been my favorite (compared to my old iPad 2).
Also, keep in mind that some of the multitasking features of the soon to be released iOS 9 will run only on the iPad Air 2, e.g. I am looking forward to the 'split-screen' option (

Note that some of iOS 9's long-awaited features are going to be available to only certain devices. For example, while the slide-over feature for multitasking can be used on older iPads like the iPad Air and the fourth-generation iPad , split view is only supported by the Air 2 thanks to its larger system memory and more powerful processor.
