Hard to explain, but the fact the ipad is so small and light, and you navigate around with your finger by pointing and gently swiping the screen makes the whole experience a lot easier - a lot more fun. it's size and shape also support using it like a book. the fact you can start a pages document on your mac and edit it on your ipad, or take photos on the iphone, and in seconds see them on the ipad or mac and display them on the apple tv. avoid the apple ipad 2, it's a relatively old model, under-powered and with a lower resolution screen. 9 inch screen and astonishingly light and remarkably thin - it feels like a light-weight book. ipad mini with retina screen. screen. much larger screen size. chip as the mini with retina - the latest and fastest full size ipad available. in terms of a full size tablet, the air 2 is the fastest, lightest and thinnest, followed by the "ipad air 1" and 4th generation ipad - and all are available on amazon. once you’ve decided upon the “physical size” then your options are around memory size and cellular option. there's versions which cover the back, or just the screen. * software including+ imovie - edit and publish home made movies+ numbers - fully functional excel for the ipad+ pages - word processor+ garageband - play a piano or a drum kit+ iphoto - edit and organise your photoswhat's not so great?--------------------------* the change in physical size means you'll need a new keyboard or replacement cover if you're upgrading from a previous model* pity apple didn't include the "touch id" to secure your passwords - but i’m pleased to say they did starting with the “ipad air 2” and the new ipad minioverall opinion---------------------it's hard to believe the ipad version 1 was released in january 2010, and there's a huge raft of "me too" tablet computers to choose from, but the apple ipad air is still the one to beat. apple packs a beautiful screen and lightning fast processor into a slimmer-than-ever shell, and battery life is very impressive"
