I think cyclocross bikes make great commuters: they can take wide or skinny tires, many have eyelets for racks and fenders, they're lighter than mountain bikes, and are built to take some abuse. The bike doesn't limit the tire pressure, the tires you choose do, and there are a lot of options. In summer I ride with semi-slick tires at 100psi, and even my sloppy weather and off-roading 'cross tires can go up to 75 for road use.
Unfortunately I think the San Jose is a bit out of your price range, it's a nice bike.
