Nope, this wasn't a laptop
Nor was the PCradio. It's only shaped like a laptop, but it's really
small like a modern netbook, or even smaller, and kind of clunky.
But if it definitely wasn't a clamshell of any size, then it could have
been the same basic idea. I have interviewed some of the people who
designed the PCradio, and learned that there definitely were other versions.
