So, my mom is still using her iPad 2 on iOS 8 right now. Even though it will be supported by iOS 9, I figure its time will soon be over. As such, I was thinking gifting her iPad Air 2 in my signature, and getting myself a refurb Air 2 (space gray) 128gb w/ cellular. While initially thinking about this, I did have a few questions that I was unsure about: Can she use it without doing Touch ID? (She isn't sold on the idea of the fingerprint scanner.) Is it a fair assumption that with the improved wireless and A8x, her buffering times on Netflix and other media consumption apps should be significantly reduced? For the cellular iPad that I would get, what type of plans are there? Are there, for instance, an "as needed / wanted" plan for a couple days at a time? Does the new Apple Sim become locked after I initially choose a carrier? Or should I be able to switch between them just as easily that I imagine switching between the data plans is?
