I've got an ipad 2. And if the ipad Air 2 doesn't have 2gb RAM, I'm going to continue to hold out. As soon as that spec is confirmed, I'll order. But not until it's 100% official. 'Leaked' images are not enough evidence for me. I want proof, then I'll order.
Wouldn't you rather see if Safari constantly reloads tabs even with 2GB before you buy ?
