if im paying 500 for a device i really wanted it had better be the top of the line product. this isnt me complaining about cores, or software its a literal integration of MEMORY in a computer. a lot of the 3gb ram devices like the note 3 can keep a TON of tabs on a browser open as well as game save-state. go on the surface 2 play a game pause it switch apps wait a couple minutes and go back and you will see it did not leave you back at the main menu u keep going right where u left off.
its almost 2014 man tablets need 2gb ram MINIMUM if its a 9 inch + device. i was okay with it on a mini retina as those users are consuers but for someone like me who is going to use the ipad for productivity apps i dont want any shortage of memory during something important.
I can leave a game and return to it where I left off on my iPhone 5 and iPad mini currently. I doubt the situation will be worse on the Air. Again iPad apps are designed to run on the iPad (normally 3 generations back). Also, I've had about 15 browser tabs open on my iPhone 5 without incident.
