“This class of system has been around for quite a while, and seems to mostly appeal to the LAN party crowd.”
Is it possible that you hold this veiw because you don’t have much exposure the type of professionals who need and use mobile workstations? I know several working animators and VFX artist who use this type of machine to take their work on the road.
“VFX work? There’s typically not much possibility to perform that in the field”
It depends on which tasks you’re talking about (VFX isn’t just one thing). Things like keying, comping and look development can all have components or phases which are done on set. I also know a few pro audio folks who use mobile workstations to record and mix live music.
