It looks like I'm the first one to reply that actually has one of the M1's.
Here's my take: I love the one I have. I was worried that I might stretch the RAM limit, but I've literally had 25 windows open with steaming video, etc. and I have never been bogged down. Not sad that I didn't get the Ram upgrade.
It's freaking fast. When I go back to my (relatively new) PC, I feel like I'm being throttled.
The size is awesome. Keyboard is very good.
I wish it weren't as slippery on the bottom. I may put something with more friction on the bottom.
I'm confident that this thing will be "future proof" for 3-5 years. I went through law school with a single laptop, and not only was that a long time ago when technology was increasing at a faster pace, but that computer wasn't at the same level (relatively speaking to the market at that time) as my MacBook Pro is.
HERE'S THE KICKER: I am on my SECOND MacBook Pro. The first one I had made it only 28 days before the screen crapped out. No trauma, no water, not nothing. I literally woke up one morning opened the PC and the screen was all jacked up. The Mac people at the store said that they had never seen anything like it and thought it was probably the chip.
My recommendation? Wait as long as you possibly can to let them figure out the problems and then go for it.
