Peter Griffin (no relation to the fictional character) field tested Skype on the Sony PSP during a recent trip to Europe. Ends:

All up a decent, free add-on for the PSP and one that makes the device even more attractive for those with access to Wi-fi at home and out on the road. One of the best Skype implementations I've seen since the classy Netgear Skype handset that did away with any need for peripheral hardware.

Hmmm. What could Skype be like on a Wii?
