The hardware is not the point
I think what Mr. Dean is getting at is that if he needs to contact someone, he won't go looking for a PC to type an email, he will use whatever communicates best. He can use his cell phone, his tablet, or something else to call, to text, to IM, to email. If he needed to create a spreadsheet, he would find the best technology to do it. The paradigm (forgive me for using that word) is shifting from being centered on what hardware you use to communicate what you are communicating. The process will become increasingly platform agnostic. I personally believe the PC in some form or other will continue to exist as long as it is a useful tool for doing what needs to be done.
