We've had the megahertz and megapixels races, now how about a megabits per second contest? A Comcast customer has posted a note from his latest bill online, showing a new Extreme 105 service that will purportedly be launching on June 1. You'll need to obtain an Arris WBM760 cable modem to make it work, while also ponying up $249 for installation and $200 each month thereafter, but such is the price for sailing in the mostly unexplored 105Mbps downstream and 10Mbps upstream currents. Guess that will have to do until Google rolls out that gigabit fiber network later this year.
