Tinker
This Fuzebox thing seems to be pretty cool… I would get one, except I’m no good with a soldering iron (or with hardware in general… I consider replacing a PC’s memory a monumental task :-).
It reminds me a bit of Pandora… which is another interesting-looking device for retrogaming, and supports Amiga emulation, among other things.
Alternatively, one could get an Asus EEE and install some emulators on it. That may be my best bet if I want a portable C64.
Anyway, there sure is a lot of cool stuff coming out these days…
