Ideas.
1) coffee/tea warmer. instead of buying a usb heater, just use the fit -pc,
I haven't added anything special to it so surface area is a bit off ("fit pc" embedded doesn't quite match the underside of my cup

errmmm...so that's the only idea I've had, but if people come up with different things to do with the heat and any attachments that can be used to make use of the heat rather than loosing it
