I know that you can't sync stuff if you have no Mac, but the thing is, I have to return my Mac Pro to the seller for various reasons, which means I will have no computer that I could use for the iPad. I would buy the iPad Air second hand and it would be reset to default and all. Would I still need a Mac to use it? I know that with older iPads this was the case, but I have the feeling I've read somewhere that it isn't the case anymore. Couldn't find where however.
