Not many. Besides the fact that people can't afford it, you can look at it the same way you look at video game consoles. I downloadedFar Cry 4 for review on my PC a few weeks ago. I asked for a PS3 review code, but, ya know. It required me redownloading a bunch of .dlls, patching it, and getting the comparability and graphics settings to work. Then I had to figure out why I was getting a fatal error on start-up, and fix that. Two hours of work. Did you get it on a console? Put the disk in, MAYBE wait for a patch, which is applied by just letting the console do its thing, and get to playing. Far Cry 4 looks better on my PC. But I'd RATHER just play it on my PS3. Same thing for 3D Printers, I think. People will always appreciate ease of use over doing it themselves, unless they consider themselves specialists. It's why consoles still have a market today, even among the constant cries of the "PC Master Race."
