Looking to upgrade from my stock mid-2010 13" MBP. I remember seeing a comparison of the 2017 models and the 13" nTB and 15" TB are apparently both better than the 13" TB. But how do the 2017 models compare to the 2016 models? Besides good battery life, my other factors/needs are... Price: not an issue, going to use it for at least a few years (but don't want unnecessary upgrades) Usage: general, browsing with many tabs, streaming, Office, occasional Photoshop, occasional Parallels/Boot Camp, may play games if it's capable Weight: all of the new models weigh less than my current 2010 MBP, so they're all an upgrade Screen size: I've only ever used a 13", and for the most part, it's been okay, but sometimes I wished it was bigger. So I'm leaning towards 15". Only concern about 15" is that apparently they're not portable... Portability: not sure what people mean about portability - weight or unwieldy size? Weight and thinness would be an upgrade from my current MBP, but it would be wider (but still fit in my backpack). F keys: mostly use the volume/brightness keys, and I have to look anyways; may do programming in the future. I'm optimistic about being able to increase productivity and seeing neat usage for the Touch Bar in the future. Storage: no video editing so storage has been fine Concerns: I hear there's tons of keyboard issues (stuck, don't respond, double-press, etc.) and that the fan is always on and noisy for the 15". What do you suggest?
