My first question is, if you mainly do writing browsing, what are your Mac specification requirements? Unless you are doing heavy lifting like 4k video editing, large image batch processing in Lightroom/PhotoShop, etc. then a MBP may not be your ideal Mac IF fan noise and heat are a concern to you.
I have a 2016 Macbook retina with the m5 (mid-level processor) and under normal workloads (aka. light) such as word processing, email, browsing, etc. It NEVER get hot, not even warm. Plus it doesn't have a fan at all, it's silent like an iPad. This may be something for you to consider.
I've had mine on for the past 5 hours for my corp work. It's connected to an external display, have Outlook, Skype, Safari and Xcel open and it's barely even warm at all. The only time I've had any real warmth from it is when on an hour long Skype video meeting and at the same time having what I mentioned before open along with several remote desktop sessions. Then the audio on Skype gets a little choppy during peaks, but the little machine never overheats. Never had heat warnings or shutdowns.
Just something to consider, the MacBook may work really well for you and eliminate any concerns with fan noise IF you can live without the Touch ID.
