I've got some dough I'm looking to spend on something. I'm thinking about keeping my late 2013 rMBP for regular use such as email, firefox, iMessages, Microsoft Word, and so on. And using my new 2016 base MacBook Pro solely as a YouTube music player for trap, EDM, electronic, and house music. I connect it to a bluetooth speaker and let the music play all day. I love it. What do you think about this setup?
