I tried a search and saw nothing on this topic but in case it hasnt been discussed there is a not so new app for the iPhone called TouchPad Pro that turns your iPhone into basically a mouse and keyboard for your MBA or any computer for that matter. It runs on a 'VNC' software or client or something like that but it works F'n great. Last night I hooked up my MBA to my Optoma HD projector set at 106" and ran TPP and it was just awesome how well it works. It now even supports multi finger control. I was going to but the keyboard and mouse but this works, for my use every bit as good and its free. The best thing is that the MBA air has the VNC built into the app...turn on screen sharing and away you go. Make sure you have BggBoss' repository on your iPhone in Installer and you will find the program. Really cool!
