You clearly missed how Linux and open-source have COMPLETELY destroyed the server and handset markets! Thank GOD the desktop market was saved from that onerous open-source operating system!
Not to mention that touchscreen computing (and computing in general) has been used for decades--and they've been evolving steps at a time--not so much innovating whole leaps at a time as he seems to want you to think Apple does. Most of what Apple did with the iPad was already being done in some form or another either by someone else or themselves already. The next thing that comes along is ALWAYS a little like the last one. Anyone remember how you had to slide to unlock a Palm phone? Multiple desktops on the Palm OS goes back a LOOONG way. Hell--Apple even did a lot of these touchscreen things back with the Newton. I'd like to know if he came out swinging the same way when EVERY graphical OS in the late 80's and into the 90's had a windowed desktop OS with office metaphors (trashcans, folders, etc., like the MacOS, Windows, GEM, Geos, etc.) when we all know they were copycats too (Xerox PARC). To their credit, every OS pretty much tried to create their own spin on a good idea. This was a GOOD thing.
