I currently have a 2013 13" MB Air 1.3gHz i5 4gb 256gb, using mostly for web browsing with multiple tabs, once in a while use Parallels, view PDFs, word/excel docs. I use it around the house and bring it to work everyday, on trips. Once in a while, it heats up and slows down when having multiple chrome tabs open with videos, etc. I usually don't have anything plugged into the usb ports, sometimes a portable hard drive to transfer files, more rarely and SD card to upload pics from a camera. I have my eye on a either a 2016 Macbook m5 8gb 512gb or 2016 Macbook Pro 13" nonTB 8gb 256gb, both are open box certified at Best Buy for under $1200. Not sure if I need the processing power of the MBP. It is similar to the MBA in size now. Seems like the 12" Macbook is already speedier than my MBA. Any recs? Thanks.
