You seem like an Apple fanboy , but let me tell you something:
Dont take an Ipad get a Surface :
- It's more cheap
- More performant (I5 Haswell)
- x86 Architecture (it means that you can use x86 apps like the one you use on laptop/desktops)
- QWERTY physical keyboard
- Storage expansion
- Unlimited updates
- Windows's flexibility
It's just better.
BTW, you talk of A8 and M8 like if these are revolutionary but they aren't.
But if you have little more bucks to spend get a Transformer (Laptop and Tablet)
And you can keep your Ipad 2, 1 year is nothing for computers: if i would change my CPU each time a new one comes i would be ruined
When buying electronics you must wait for the best occasion and for real revolutions.
