Hi ! Just a couple of weeks a brand new Ipad4 wifi+3g 128GB by a nice price (500 Euros). Since the Ipad was a gift, it is still unopened. However I got a chance to buy the iPad Air with the same config for more 290 Euros. My only fear is that the iPad 4 comes "obsolete" very soon due to eminent arrival of a new Ipad Air. I still have the chance to change the iPads. The question is : would you do it having in consideration the price difference and the advantages of the Air over the iPad 4 ? Thanks !
