Yep, if you manage to connect at a nominal 300Mbit/s on Wifi, you can just about scrape 100Mbit/s in practice. You basically need a 40MHz band of 5GHz Wifi, which is probably what you're using, and which is why it's not interfering much with the other APs, most of which probably only broadcast in the 2.4GHz band. Also, the number of available frequency slots in the 5GHz band is much bigger. Too bad the older iPhones don't support it, and most APs can't use both bands simultaneously (current Airport Extremes do!). Still, that's 3-4 times slower than USB (in theory).
