Greetings Folks, As the title suggests, I have a 2010 refurb iMac coming. I also have an iPad. I'm thinking of selling my 2011 MBA. I'm graduating in a few weeks so I won't have the same need for a portable solution and I'm a pretty good typist on my iPad so long emails etc aren't a problem. I've nearly convinced myself that my MBA will no long be necessary. Is therea point I'm missing about why I should keep the MBA?
