       | 
       | I see comments like this in various reviews. Are there really
       | people out there who would replace a Macbook Pro M1 or M2 with a
       | M3 just to get something a bit faster? What are they doing that
       | is so performance critical?
       | 
       | My last Macbook Pro is a 2014. I still find it usable for
       | development work, and I'm only replacing it because of other
       | hardware failures.

           | Over the years I've gone through a Core2 MacBook, a 2011 MBP,
           | a 2015 MBP, and now a 14" 2023 M2 Pro as each wore out
           | physically over the years. Generally the charging systems and
           | keyboards degraded severely by the 5 year mark. The 2015 had
           | all those problems as well as janky graphics issues, but I
           | used it until its SSD died recently.
           | 
           | Aside from performance it's hard to overstate just how quiet
           | the current MacBook Pro is. The 2015 got noisy pretty easily
           | especially if I had to switch to the discrete GPU, and
           | anything heavier than 1080p30 in Firefox would cause the fans
           | to go bonkers. By most accounts the last of the Intel models
           | were worse. This one? After a few hours of transcoding video
           | the fans still only spin up to a quiet whisper.
           | 
           | What I don't hear anyone talk about is the rigidity. You
           | could hear the 2015 creak and flex if you picked it up with
           | one hand. The 2023 just feels like a solid chunk of metal.
           | 
           | For all of its warts, this is probably my favorite hardware
           | of the bunch. The software (macos 14) is utter garbage
           | though. That's the culmination of lots of poor design choices
           | over the years and nearly non-existent quality control.

         | even after half a year's use. At that value, it basically felt

         | (Max-level processor, bigger SSD, quite a bit more memory).
         | 
         | 3. I thought the darker color looked neat. That said, it's much
