I considered buying one of these at the time (as a happy HP 32S calculator user) but after playing with a colleague's one I decided not to bother. It was neat but there were so many compromises and inconveniences that it made the thing difficult at best so I figured I'd leave it a few years to see what happened. My colleague, after the initial amazed and shiny period wore off, just used it as a terminal for futzing with routers with in the end. This was a pretty expensive solution because we already had piles of old Wyse terminals floating around unused.
