So far in this thread it looks like there is one person that claims to only use Classic Amiga computer(s) for all of his/her computing needs and never uses any PC's, or Mac's, AND 1 or 2 others that use a PC or Mac controlled by their Amiga via RDesktop, which I would consider almost qualifying, as they are on their Amiga doing all of their computing and the PC or Mac connected via a LAN and controlled by the Amiga is sort of like just another co-processor accessed by the Amiga to give it more functionality.
I would like to try out using just one Amiga computer for everything plus the RDesktop connection to my 3.0GHz Core2Quad PC for certain programs and tasks that need brute force. My most likely choice would not be any of my Classic Amigas though, it would be my 1.5GHz G4 Mac Mini running MorphOS2.5. I have not tried it yet, but I am pretty sure there is a version of RDesktop that is native for MorphOS, or at least runs well on MorphOS2.5.
That would probably be a better solution than the hassle of running more cables and finding a FVM switch that will connect to the two or three computers I want to use most often from one desk location in my home.
