Most of the MSI Wind U100 clones can be overclocked by flashing them with the latest U100 bios. (Giving an option in the bios to overclock by 8, 15 or 24% iirc) and by pressing the Fn+F10 keys, you can toggle the overclock on the fly. I've got a Medion E1210 with the MSI U100 bios running at 1.98GHz (24% OC), with a 500GB hard drive, 2GB RAM, and dual booting Win 7 Pro and Snow Leopard. It's awesome for traveling; it's so small and light you can just chuck it in a bag with some clothes and off you go!
