I'm typing this on a MagSafe laptop. I don't like MagSafe.

The cables fray and the MagSafe tips wear out, that means buying an entire new charger (or soldering on a donor cable), I'm on my 5th or 6th. The surfaces get dirty, and because they just butt up (rather than sliding) they become high resistance and heat up.

If MagSafe 2021 doesn't fuse the cable to the charger brick, then I might consider it. The fickle electrical connection is inherent to the design though.
