Just bought and am now returning an iPad Mini. Had great hopes for it, but it is incompatible with my MacBook. It may seem unbelievable that an Apple device is incompatible with another Apple device, but it seems to be the case-I spent nearly two hours on the phone with Apple support, and they couldn't help.
The issue is that my MacBook runs system 10.6.8 because I have, and use a number of music programs that don't run on any later OS. The Mini doesn't even show up on the desktop when I connect it and I can't transfer files from one device to the other. And no, I am not installing a second operation system on the laptop, or any of the other work-arounds because it's not worth the extra trouble.
Also, it is not as quick as my iPhone, and the apps(particularly the third party ones) are slightly different, which is a pain.
