I just received my refurbished, 2017 rMB (base model, 8GB / 256GB) today. So far, I love it! I'm still getting everything set up on it but some initial thoughts: 1) the size. WOW. I'm coming from and will still be using a 2014 rMBP, which is "only" 3.4 lbs. When I bought the 2014 rMBP I was coming from a cMBP and it seemed light in comparison, but I guess our expectations for portability get higher and higher over time because my primary use for buying the rMB was wanting something more portable since I carry the laptop to work every day. This thing is compact! 2) the keyboard: I had read A LOT about this and was nervous about it. I find I can type very accurately on it. No issues. The only thing I am still getting used to is the "clickiness". It's louder than my previous keyboard, or at least a different sound. I'm still unsure whether I'll get the stuck keys people have talked about. Is the 'clickiness' something that changes or that one just gets used to? 3) for anyone curious about refurbished computers and batteries: out of sheer curiosity I checked the number of cycles on the battery when I first started the computer. It had 4. So, not a new battery (which I knew was likely) but what I consider an appropriate amount, especially given the savings + the fact that I have the regular Apple warranty. 4) I have both the 2014 rMBP and 2017 rMB in front of me right now and it's interesting going back and forth between them. In basic usage (for me; office/business-type use) I don't find the rMB slow at all, even going from one computer to the other (typing this on the rMBP right now while setting up some software on the rMB). It'll be interesting to see as I multi-task more on the rMB. Do you use a keyboard protector? (One of those thin clear pieces? I've never used one on my previous Macs but am wondering if I should on this one?) Should I disable throttling to prevent overheating?
