Hi guys, Im looking to buy a keyboard for my new ipad air but dont want the bulk of having it permanently attached. Im thinking of buying a keyboard in the style of the logitech ultrathin cover and a shell compatable with a smart cover, like this one. Have any of you guys tried a combination like this and if so how did it turn out? Also are there any recommendations regarding either the keyboard or the shell? BTW I'm in the UK, so slightly limited with some of the options (I'm looking at you ZaggKeys Cover...) Thanks!
