Haha... yeah... I bought the m5 this past summer, replacing my surfacebook as I wanted to have a Mac across all devices again (iMessage for me is the killer app, among a couple other things). Anyway the m5 was awesome for carrying around.. loved it. But it really does not meet performance expectations for my usage (as previously described).
After research I decided to get the 2016 MBP but wasn't sure which one... Portability is great for me, but I'm not really sweating an extra 1-2 pounds in my bag. I'm more worried about the actual footprint of the device... airplane tables are small, cafe tables are small sometimes, and a dinner table with 3 coworkers with their laptops out is also small...
That said, I love the idea of a large screen and the increased viewing I could have, while still being able to read, on a large excel, working inside a Prezi, or 2 word docs side by side.
Just not sure it is worth the "cost" of the size increase... not really the weight.
I got the 8gb version of the 2016 MBP and I indeed do hit 8gb+ regularly when working during the week. I have no doubt the increased SSD speed is meaningful after reviewing benchmarks of it compared to the rMB. I'd say most impressive to me is the increased screen size.. which again leads me to consider returning during my window (45 days due to Best Buy Elite+) for the 15".
