I have a question about whether upgrading to a gigabit switch makes sense for my situation; googling indicates that while at least in theory 802.11n is faster than 100 MB ethernet it's not likely true in real use, other arguments say that upgrading the switch makes sense from a throughput standpoint.
i personally get much better performance over a gigabit ethernet than via 802.11n; classic case is that when i import photos into Aperture, i have it back up these images to a LAN-attached machine; i haven't timed it but when the primary machine is on wifi a big batch will seem to be an order of magnitude slower than when both machines in question are on gigE
in case it matters the two machines connect via gigE ports on a first-gen (non-simultaneous dual band) Time Machine — that may affect my wifi results; the third gigE port on the Time Machine goes to a cheap TP Link 5-port gigabit switch which serves a laser printer and ad hoc connections
in short, if you do big transfers between your laptops, a gigabit switch is worth it; they are very inexpensive
