I recently bought a refurbished rMBP 2015 13" from Apple. I currently have a late 2011 MBP. I've been playing with the rMBP, and noticed a few things about the rMBP that has been bothering me. a) The keyboard feels much smaller, and the keys feel "squishy"/less of a mechanical feedback. b) The trackpad feels too "soft" (hard to explain), and clicks aren't as feedback-y as the 2011 version. I also sometimes have to click again or harder – it feels like there's less "grip" than my 2011 MBP. c) The MagSafe power plug kind of feels flimsy, and falls out if I move my laptop too much. This didn't happen with the 2011 model. d) Even though "auto brightness" for my display is disabled, my screen seems to kind of "adjust" and get darker/brighter from time to time. It may be just me, but the 2011 MBP felt more solid/less flimsy in some ways. Having a much better display is really nice, and it's also nice having Handoff/AC WiFi, but I don't know. I got this (i7 3.1ghz, 512gb, 16gb of RAM) for $1779+tax, so not bad, but I'm not sure – the laptop just feels softer and less of a tank compared to the 2011 MBP, if that makes sense. Are these issues normal for the rMBP 2015? Many thanks!
