Mentioned elsewhere that we had an iTunes issue some years back. The online tech support couldn't fix it and it got escalated immediately (not we'll callback at some point if we can be arsed) to the next tier support in America.
Had this bloke on the phone who literally must have been Mr. iTunes - knew the thing inside out and backwards. Got our issue resolved via remote access onto our MacBook in about ten minutes.
Massively overpriced pieces of kit that are above average and out-gunned by the competition. But the quality of support is unsurpassed and iOS is just great to use. If I could get a new gen phone, take it out of its box, wipe the Little Green Robot from it and replace it with iOS - I'd do that tomorrow!
