A month ago I had an old thinkpad lying around and out of boredom I bought a new ssd and installed linux on it. I have been using this laptop ever since instead of my rmbp15 (mid 2012). To be honest this thing has 1/3 the battery life of my mbp, is slower, does not have retina and its thicker. But in terms of os I don't miss anything at all. Facetime is a huge blow. I am using google hangouts now with friends but frankly its not as good as facetime/imessage. In terms of productivity I might even be faster on Linux than on OS X because of my choice of UI but thats tough to say. I also noticed that pixar and hollywood are all using linux. I was thinking I could still get some money if I sell my rmbp. Should I do it?
