For the past several years I've always used an Apple remote to give presentations on my laptop, and was totally happy with it -- it was simple, easy, and (most importantly) reliable. Unfortunately, with the lack of an IR sensor in the MacBook Air, that's no longer possible. I've never used any other remotes/presenters before (and no iPhone, etc) so looking for suggestions as to the best solution. The two possibilities I can think of are buying a USB IR adapter for the MBA, or going the more conventional route of a Bluetooth presenter. The IR option is obviously a pain and just band-aids the problem, but the Bluetooth option makes me hesitate because I know some remotes drop the connection or similar, and that's the absolute last thing I want to have to deal with. I don't need hundreds of buttons and features, I just want a small, reliable remote. Suggestions?
