I agree regarding the demise of the MagSafe connector for power. Obstensibly, the idea is that you can now charge your laptop on any port (a bit of convenience), but the MagSafe was a stroke of genius that hasn’t been duplicated. I can’t count the number of times the magnetic connection saved my MBP... and contrary to the issues others had with the cords fraying... I never had one completely fail. I did have one have the outer sheath crack on my old white Macbook adapter - fixed with heat shrink.
My new MBP (I’ve had it less than 2 months) works well enough - but the jury is still out with 4 USB-C connectors and a headphone jack .... no SD slot, no other forms of connection... I have to have a dongle to connect just about anything...
FYI... You can get what are essentially Magsafe cables for USB-C and several other connectors now. There’s a small detachable magnetic piece on the end of the cable that plugs right into your USB-C port and attaches/detaches to or from the rest of the cable. Several companies are making cables like this now and some may be better than others, but in any case you do still have a magsafe-like cable as an option.
My new MBP has the same set up; I miss the SD card slot more than I anticipated. Someone in the design team went for style instead of workhorse design.
MagSafe connectors are what most adult toys use, by the way. Almost none of them have plug-in power ports.
