I am so glad I came across your post, but sadly only did so after I had posted this http://forums.linuxmint.com/viewtopic.php?f=18&t=184157
iMac is one thing, MBP another? Or are there few differences?
In my case, I might even also get a used iMac and use a tablet when traveling to meetings. Your post just opened up that line of thought for me.
