Today is hot, ridiculously hot, in San Francisco (99 degrees hot), and as much as I love a good heat wave, this geek's gotta get herself a desk fan. And why settle for an ordinary fan when I can have one that looks fun and tropical like the ones below? And for extra geek points, they are both USB-powered — no batteries needed! The yellow Holywood USB fan costs $9 and includes a flexible neck so you can get it at just the right angle, while the blue USB flexible fan is only $7 and is a low power consumption fan. In the meantime, excuse me while I go douse myself in cold water.
