Same here, I had a Samsung Tab 2. 7" but don't care for 'mini" screens, just got the Samsung Galaxy Note 10.1 and it's nice to browse error free, and more importantly shop without the browser crashing, it happen mid-purchase on my iPad Air and my transaction was missing from the vendors cart, but third-party billing had billed me anyway, I had to make phone calls, the vendor said they had no record of my purchase and agreed to reverse the charge. And I had to make the purchase again later on the desktop.
I love the size, screen, feel and battery life of the iPad Air, and I was hoping Apple would address this issue in a timely manner but they haven't, and the iPad Air is just too unreliable for transactions that I can't trust using it, I may stick with the Samsung and just give-up and return the iPad Air. I had talked to a Guinness and explained it's continued crashing, they wanted to swap it out but other that have say it's still happening, they advised to reset as new and all the things I'd already done, so he told me I can return it ...so I think that 's what I will do.
