I’ve seen cooling stands for laptops before, but they’re usually too big to use with netbooks. The fanBASE from Scosche is designed to be used with netbooks, and it’s portable so you can take it with you. There’s a USB-powered cooling fan and a 3-port USB hub in the base. The legs fold in and the USB cable stores on the bottom for travel. The fanBASE is $24.99.
