My 16" MacBook Pro arrived on Monday. This is easily the best piece of tech I've ever purchased. I can't recommend it enough. The display size makes a night and day difference for my dev work compared to 13". This thing actually feels like a 'desktop replacement'. I could comfortably work for hours at my desk or outside, whereas being in laptop mode with my MacBook Air was a real struggle on my eyes.
I had no concern for the display quality before purchase (as the Air was already excellent), but wow, the "Liquid Retina XDR" display @ 120Hz is a noticeable step up and makes my 32" 60Hz monitor so much less enjoyable than before.
Also, the battery life is absurd. It still said 100% after working outside for over 30 minutes yesterday. The M1 Air had exceptional battery life but this seems far superior (although just an early impression over a few hours).
