Not quite
all of the way back yet, but it's very, very clear the situation is improving, and markedly so. So far things seem to be tracking very closely with what Eben Upton told us in those last couple of interviews. It's obvious we're near the "tipping point" where supply (and prices) will be back to normal.
That said, this whole experience did motivate me to at least start experimenting with some alternatives. I finally ordered an Orange Pi board, as well as a couple of RISC-V based SBC's to start dipping my toes in that water.
