I finally had no choice but to replace the 2013 vintage MBP (excellent machine) and I nearly decided to go with a PC instead. Part of me wishes I had and I may still return this. My bottom line: do NOT upgrade if you can avoid it, but if you *must* then recognize that it will be a step-down in usability. For me, it is the most annoying Apple portable I have bought since the Powerbook 5300 (which is the POJ product that caused me to switch to PCs in 1990s).The Good - much faster, nice screen, SDD is very fast, thin and light with good battery power, and excellent speakers for a laptopThe Chicken Guano:* Apple no longer includes the little extension for the power adapter meaning you have to buy one for an extra $20 if you want to plug in to any outlet that will not fit a heavy 4" power block (total guano for the most expensive laptop on the planet)* Touch bar is much worse than a useless gimmick, it makes it difficult to use the actual function keys when you need them - you get to play the "where is the brightness key now?" game (it's on the right, no its on the left, wait where is the volume, it is on the right, no middle, wait it is moving around, now it's gone, you have to click x to get it back because you adjusted the brightness if you want the volume - good luck doing any of that without staring at the keyboard and long for the days when you could thoughtlessly hit the mute button or adjust the brightness)* Touch Bar will activate if you rest your hand too close to it, causing you to jump between web pages (for example)* At least emojis are always nearby (stupid)* Hey Siri needs a different command to distinguish it from the phone/watch or else it is basically useless (which means it is useless) - Apple, try Hey MacBook or something, Siri will not care, it is not a person, it does not actually exist, sacrificing usefulness to maintain this fiction is stupid* The Ports - this has been beaten to death but it is still lousy and having to keep adapters and dongles and whatever plugged in is more than just inconvenient, it is makes the computer less comfortable to use and as near as I can tell, most adapters are actually a step *backwards* in speed of charging etc with nearly every device Apple or anyone else makes (it seems to take at least 2x as long to charge the iPhone through the USB-C to USB adapter)* The mag-safe power adapter is gone, this computer will one bay go crashing to the floor because of the dog/child/errant foot. Losing this was stupid, stupid, stupid* Keyboard is still not great and is still noisy* Track pad is too large, takes up too much room and gets in the wayI may still send this back in exchange for a PC. The many years of projects on Apple software is the only discouraging me from doing that. I may just take the performance hit on the MacBook Air and buy an external SSD.
