- less precise trackpad than my 3 year old rMBP
- palm-sensitive trackpad
- failure that politely states that I need to reboot (if I try to use fingerprint reader to login too quickly after opening the laptop)
- unplanned reboots due to updates
- laggy and choppy video on a single external 4k monitor (compared to no apparent lag when the old rMBP drives 2x 4k monitors)
- very slow Bash (ubuntu subsystem) - but at least they're making an effort
- Cortana seems less effective than Siri, and she wasn't great; and Cortana still only uses Bing search and displays results in Edge browser
- louder and more frequently spun up fan compared to old rMBP (which was also an i7 with an Nvidia GPU)
- occasional crashes when opening laptop or logging in
- very slow unzipping of files (on new 1TB PCIe SSD), regardless of whether 7z is used or built-in unzip is used, and regardless of where I unzip/extract to
In summary, it's just a sexy little game machine. In that regard, it does pretty well. You do have to wear headphones to game because the fan is so loud. And you can't play on an external monitor... too laggy and limited to 30Hz refresh.
Too bad Apple no longer caters to my crowd. Thankfully this old rMBP I use is still running well (despite the screen covering deterioration in weird spotty ways).
