Should you buy the iPad 2 or the iPad Air? We help you decide in our iPad buying guide, covering specs, price, features and more. Apple has unveiled its next full-size iPad - the iPad Air - alongside a new version of its iPad mini with a Retina display. The iPad Air is now available to buy, but we haven't been got an onsale date for the Retina iPad mini (we've simply been told 'late November' by Apple). Here, we help you decide whether you should buy the iPad 2, which is still available to buy and comes in at just £329 for the WiFi model, or go for the more expensive iPad Air (which starts at £399).
