LOL…you are so full of crap. The A5 Geekbench scores are 258 for single-core and 494 for multi-core. The A7 Geekbench scores are 1,477 for single-core and 2,677 for multi-core. Your iPad 2 is NOT imperceptible in many tasks to an iPad Air. The A7 does everything faster than the A5. You might want to learn how to spell imperceptible before using the word. Four of them under your care? Are you babysitting them?
