The only advantage it gives is a marketing checkbox relative
to Microsoft OSs.  One that would not need to be there, if
Microsoft didn't support it.

I can't do that, so long as Microsoft support it.

I don't understand this statement; when I buy a PC, do I not pay
for the ISA card edge connectors and copper cladding on the PC
board, as well as the resin that makes up the board?

If you can tell me how I can aboid that (point me to a vendor of
competitively priced machines which omit the bus, please!), then
let me know.

So, promoting ISA is what locked us in?

I don't believe this, but even if I did, how does that save
me, as an OS vendor, from having to support ISA?

Or dragging the rest of us down with you...
