I'm not sure what you mean by "3d graphics won't [work]", they do just fine. Transferring files/settings is also a non-issue. I think it's been a long while since you looked at or used a Linux desktop. They have come a long long way in the past 5 years.

Not sure how it can be any easier other than getting a computer pre-installed (which you can now too, but, admittedly not as common as I would like). I mean, you have to put a disk into some hardware at some point and click some install button...
