Mine actually showed up yesterday. m7/256 silver. Two days earlier than Apple predicted and a day earlier the FedEx had on their tracking website. Got it all set up last night and it's working well. Not sure I notice a huge difference in the apps I use (Safari, MS Remote Desktop, Scrivener, Chrome, Mail, Parallels with Windows 10 Pro 64bit VM.), though the benchmarks are all in line with what I've seen online earlier this week so it is definitely faster. I would have to say that the most notable thing I've noticed is the battery usage/life. Absolutely better than my 2015 model, at least so far. I've been on it off and on for about 3-4 hours today and it's just now dropped to 89%. (it was at 100% this morning when I left the house.)
