Being able to repair is great. I am bothered by the fact that

Sockets cost money.
Is that really their excuse?

There's a little discussion there. It's more than the cost of the socket.
With modern SMT processes a pick and place machine puts the components on
the board. Usually they are held in place with solder paste although
sometimes adhesive is used. Run the board through a reflow machine and
you're done.

Think about soldered on laptop memory versus DIMMs. First, the DIMM is an
entirely separate manufacturing step. Then you need to solder the slot and
retained hardware onto the motherboard, which is more complcated than
dropping on SMTs. Finally you have to insert the DIMMs.

They don't show it but presumably in a real operation the robot is picking
the DIMMs out a a cassette or some other fixture. More steps, more money.
