Team - NEED YOUR ADVICE. My workflow: email, browsing, advanced excel for number crunching and programming, MS Office, and browsing. Usually, I have excel, slack, airmail, 2 safari windows, (3-4 tabs), powerpoint, calendar, and preview open at any given point of time. I work from home for own business and frequently travel. I am currently using rMBP 15inch (2015) - great for desktop but cannot carry out in house or for travel and battery life is not great (get 7 hours). I need 256gb hard drive space and 8gb ram - am fine with one port as most of stuff is in cloud. I am struggling between following options: Sell my rMBP 15 inch and ... 1. Just get a macbook 2016 m7 and connect with external monitor (m7 seems sufficient for my needs) 2. Get macbook pro 2015 13 inch as it is indeed less expensive than macbook when I chose refurbished model. Indeed, 15-inch MBP is also now cheaper than macbook. 3. Wait for 2016 release of macbook pro but that seems to be in year end. Alternatively, keep rMBP 15inch and also buy macbook m7 (very expensive endeavor) but love to hear if anyone has invested in such workflow.
