Hi guys. So I am a college student next year in Industrial Design. I really am stretching a tight budget after I got a 27" iMac, so now I am either going to wait for the MacBook Air update or get an iPad and remote desktop from my iMac to the iPad to take notes, so I would have to buy a keyboard case for it. Is this a reliable route to go? I really need as much better life and portability as possible. Also, is there a keyboard case you guys would recommend? Also, when I am using Remote Desktop, is my iMac's screen on so everyone can see what I am doing?
