Are you saying that mobile devices aren't capable of playing games of the same graphical and technical complexity as a Windows 95 game? I assure you that isn't true.
No, what I'm saying is that you will never see an iPad displaying the same complex scene a 500W-PC with a double-SLI card has no problem of taking care of. There is and there will always be a large gap between what you can do in fixed based devices and mobile systems, because of their inherent design goals.
