3 reasons: (1) dumb switches are called dumb for a reason; if the ASIC has
problems it will just drop or mangle a packet and leave it to a higher
layer to recover. If most of the ports are running at high speed there's
fewer opportunities for the ASIC to get it wrong; (b) if you plug 10 meg
hardware into 10 meg hardware the possibility of problems with 10/100
negotiation are eliminated, not to mention reducing collision errors from
fewer 10/100 transitions; and (iii) for the AR amongst us, it makes the
idiot lights on the switch look untidy.

Consumer grade hardware is built down to a price. Commercial grade
hardware is built up to a standard.
