Sorry for another thread like this but I need advice. I have an ipad 3 and want to upgrade. I can't seem to decide between the ipad air and mini. I have a voucher for £20 off at Tesco and could get the air for £379.99. There could be a wait for the mini if stocks are tight. So should I bite the bullet and buy the air which should have plenty in stock and get the discount or pay full price and hope to snap up a mini?
