Well, I'm ready to say goodbye to my mid 2012 15" MBP. It's been wonderful, but I'm tired of lugging this brick around! I was thinking of the 13" MBP w/512ssd and 16gb RAM. Here is my dilemma...I love the finger print reader and the touch bar looks cool. But will I use it? Someone said the plastic on the touch bar makes the system get very warm?!? The second question I have is should I jump to the I7 over the I5? Will I notice a difference? My current MBP is 2.3 MHZ w/an I7. I'm not techie at all and I would appreciate any and all advice...Thanks friends, Jenny
