Presenter & Macbook Air

Hi guys,

Having real problems trying to get a presenter for my MBA.

I bought the Logitech R800 but it failed. Been trying to look at others but there is so much confusion out there as to what works and what doesn't.

I was told Kensington works with MBA but then I just seen a post saying it didn't for this guy. I dont want to buy again and be let down so I thought I would ask you lot.
