I mentioned the PCB auto-router in my earlier email, but when talking
about rendering speed, I was just talking about how long it takes for
PCB to draw a screen-update whilst manually editing the board.

You and Bob seem to have thought I was concerned about rendering speed
_during_ auto-routing. You still need to look at the auto-router
results, even if you don't care about the intermediate steps ;)

From Bob's comments, it seems that perhaps Altium isn't as polished as
I've imagined it is. There will still be momentum behind it though, due

Tool familiarity amongst the designers
The designers already bought Altium at some point
Existing symbols / schematics which can be reused
Production tested and optimised footprints

That is probably true.
