You are aware that you can run Android itself on PC's right ?
Yes of course.
That there is an X86 build which runs just fine on commodity PC hardware ?
Yes but what does that have to do with Chromebooks? The defining characteristic of a Chromebook is that it runs ChromeOS. You can get x86 Chromebooks onto which you could install Windows and say run Solidworks but you wouldn't then go saying "Chromebooks can run Solidworks" because the very thing that differentiates a Chromebook from any other laptop is that it runs ChromeOS.
The line between PC and device isn't as clear-cut as you suggest and that was my point.
I don't think I suggested anything like that.
