I have an I-Pad 2 and an I-Pad 3. No problems whatsoever, BUT: In the space of 2 days, both my laptops ( one used for each I-Pad) have stopped working with the dreaded blue screen. We had a huge power storm & I'm afraid they both got fried. One was a Sony Vaio running XP and the other an HP running Vista. They are both too old to worry about, but my question is: 1. I want to replace with Mac Book Air or similar. Will this create problems with old pc's still on Apple web site? 2. Can I expect any problems on this approach?
