Your own words:
I give sony bonus points for the vaio ultralight designs - other than that - name one innovation the pc industry provided that directly and favorably impacts the end user experirence that Apple didn't release first.
Yet many times you batting things down because the PC didn't invent them first, but some Non-Apple company did. So on that you changed things around to suit your own needs.
I gave the IBM Thinkpad Butteryfly keyboard, but you poo-pooed it, and then changed the argument so that instead of the end user experience it was now about the UI.
The Lightpen was bundled on some hardware and software packages, and it did impact end user experience, yet because it isn't included on 100% of the systems out there, you poo-pooed it. Again you are changing the terms to suit your own needs.
As a result, I refuse to discuss the issue any further with you.
