Perhaps not compared to memory, but that gap continues to look smaller and smaller.

The new PCIe/NVME drive's bandwidth looks to be within 1(-ish) order of magnitude of ddr3. Apple is claiming ~3GB/s read ~2GB write and iirc 1600mhz ddr3 is somewhere around 20GB/s rw. I don't know what the latency numbers are, but I know the NVME/PCIe bus is a dramatic improvement -- not saying it will be measured in nanoseconds, however.

I have some fusion ioDrives at work that have about 3GB/s r 2.5 w with ~30 microsecond latency over the PCIe bus. Exciting times we live in for io :)

You don't need that keyboard or mouse. And, as you said, they are wireless. But the real point is they are not needed. It's a laptop. No need to carry an extra keyboard around with it. Just keep those things at home, I would think. And the adapter for their wireless wires or whatever. Not a problem.

>A gigabit ethernet adapter.

WiFi? This one could be handy, in very rare cases. Better bring a cable too. And a small hub or switch in case there are no ports available. And power for the switch. And a second cable and adapter in case you want to do 2x 1GB... hmmmmm maybe this being prepared for everything bit can be carried too far, no? But let's blame Apple.

>Mini-DP x2 adapter, for my desktop screens. I may be able to leave those attached to the screens, though.

There. What you just said. Leave them attached. No problem.

>I'd need another one for home in that case.

Yep, not a problem.

>Power adapter, HDMI adapter and two USB-A, for attaching to any external screens, speakerphones, and webcams when in a conference room.

It already comes with a power cord. What laptop doesn't?

It has a camera built in.

It has speakers and a microphone.

For connecting to the big screen, AirPlay is wireless.

If all these don't work for you, any decently equipped conference room or company where the room is located should have the proper equipment available. Otherwise you have to make do with the fantastic quality of the built in AV components of the laptop. If they don't even have a screen, are you going to bring one just in case? Of course not; you'll present off the screen on the laptop, in a pinch. As with all the other stuff. But in most cases you won't even need to because they'll have the proper equipment on hand.

And you forgot about conferencing tools like Google Hangouts, which can be freely used by everyone if they simply decide to.

>If I include my hobbies, I will also be needing a USB-C to USB-B cable for my USB hub (or a few new USB-C to Mini- and Micro-USB cables), and a SD card adapter.

Those can stay at home. If you go on a trip to take lots of photos on an SD card, then of course for any such trip you are bringing an SD adapter. Big deal.

To sum up, of all these I see precisely one that while very optional might be nice to have sometimes: the ethernet adapter. The others seem like just moving the goalposts to justify hating on Apple.
