The moment has arrived: my old good MBP 15", a late 2011 with 8 Gb and an SSD, is ready to be replaced. I want a Retina display, and I don't need a 15" screen anymore, since portability is more desirable than screen estate. The duty I'm going to throw at my new notebook will be quite light: office, Mail, a lot of Safari browsing and video watching, streaming from the net and from downloaded files (VLC my favorite player). So I'm very debated: the old good MacBook Pro 13", more powerful and versatile, or the glamorous MacBook ? Computational power between the twos is very different, but I don't really need so much power. I'm a little bit worried about watching videos (and I mean movies also) on the MacBook: it is a fanless cooled notebook after all. I know, you can't have the right answer for me, but any advice is more than appreciated.
