Hi all, I know the MB vs MBP debate has had a lot of threads, but I ask anyway: I'm a literature professor writing a big book this year that involves generating and consulting lots of documents (mainly word files, some .pdfs). I need to replace my 2009 13" Pro - and am torn between the retina pro and the new macbook. I'm not bothered about the port issue on the MB (I mainly use wireless for storage and printing), and since I use a lot of libraries and archives I'm quite excited about the portability factor. But mainly I'm wondering if anyone has used the MB for long, intensive writing sessions - lots of toggling between documents, looking at the screen and typing for hours, etc. I'm willing to get used to the new keyboard, but would the extra real estate on the 13" screen make a serious difference here? Would the better CPU make any difference to heavy word processing/pdf use? I want to make sure that I could actually get serious work done on the macbook (and that it's not just a glorified facebook machine). Thanks!
