Mate - you are singing from my hymnbook!
There is something amazing about having an ipad2 and being able to present to a boardroom while standing up, moving around and wirelessly presenting - and now I see Macbook Air is really penetrating the office suite - the same is needed - for professional presentations there is nothing better
My only question to you is - now that you can do this with an ipad 2 - and most boardrooms only have VGA projectors - have you figured out how best to get an Apple TV2 to connect to VGA? eg: HDMI - VGA or some other connection?
I think the ability to somehow easily connect an Air TV2 to a VGA and mirror desktops from a Mac will cement the MAC way up the food chain
I recently had the problem of recieving an apple tv as a present and not having a tv that supported HDMI. So i bought an HDMI to VGA converter on amazon to hook into my projector and it works great, Here is the converter: http://www.amazon.com/Audio-Converter-Support-1080P-Output/dp/B0057UNQ18/ref=sr_ 1_10?s=electronics&ie=UTF8&qid=1325278757&sr=1-10 This DOES convert the digital to analog, don't be fooled by the silly cables on amazon and such THEY WON'T WORK
