This doesn't speed up all Web browsing, because some of the places I surf have slow servers. But oh boy does it speed up the higher-end sites, where the delays were due to getting bytes through the network rather than off the servers in the first place. And Remote Desktop into work now just flies.
Which is a Good Thing, since local gasoline prices are now pushing US$4/gallon. Spending a day or so a week not driving to work is looking more and more attractive.
