Of the several objections to my comment people have registered, this seems like the best one: on reflection it seems likely that an 85W laptop's daily use is likely to be around 1 kWh (maybe 2 kWh if driven near capacity 24 hrs), which is on the order of $5-$10/mo. So for things to come out something like I'd speculated, either older workstations would need to use much more power (5-10kWh) or the manufacture of something new would have to involve much less energy than I'd guessed.
