I've got the fourth generation iPad and I'm having issues with the home button. It's taken me as many as five presses to get a single response from it and sometimes, when I press it once, it registers two presses, bringing up the list of open apps. Anyone else seen this ? I called the Apple store, who said that they would probably just swap it. That would be ok if I wasn't likely to get a 'refurbished' one in return. I have to say, while I'm mostly pleased with the device, costing £500 and being only two months old should mean that it worked perfectly for a lot longer.
