Air pad 2

Went to the Apple Store today to buy the new air pad 2. 64g they don't do the 32g anymore. And my 16g I pad air that I bought last year was running out of space. They offered me £150 for it . It was £399. Anyway they didn't have any . So I went to John Lewis and got one. With a 2 year guarantee. Not opened the box yet.
