[pornel]

Everything other than performance per Watt is not great.

• The boot process is very locked down, and is unfinished/buggy. My M1 MBP is acting up in ways that previously would have been solved with SMC/PRAM reset, but M1 doesn't have these and NVRAM can't be reset. I had to reinstall it via DFU mode. It felt like jailbreaking an iPhone.

• The hardware has a poor implementation of Thunderbolt with missing features and incompatibilities. Not only it supports only one external display, but only one specific port, and in multi-port docks you can't chose which one it picks. Some external disks benchmark poorly with inconsistent and slower-than-expected speeds.

• Having ports only on one side is more annoying than I expected.

• It's clearly a "rev.1" machine, and these usually age poorly and get dropped by Apple quicker than later, mature revisions.

• It's very fast for a 25W CPU, but in absolute terms power-hungry desktop CPUs are still faster. So my buggy M1 is gathering dust, because right now I'm not traveling anywhere, so I can use a desktop computer that is faster.
