Strangely, something changed slightly for me. I configured a macpro on the apple education store (US) (moved to 2 gig ram, airport, bluetooth, wireless keyboard/mouse from the base configuration) and the price dropped by a whopping $2 from before the updates. I can't figure out where the $2 came from since none of the prices seemed to change (must be the wifi/bluetooth option or keyboard since they are the only prices that don't end in $9 amounts, iirc). not quite the configuration I ended up with, though (moved to a 500 GB disk in the first bay). Seems like the educational discount applies to certain options as well, since the discount is more than $200, which I believe is the discount off of the base configuration.
Cheers.
