hmm... only if I kid myself that the mobile phones (even the smart ones) are actually computing devices on which "I can compute whatever I wish to compute AND the way I can compute on a PC". Most of the ARM devices sold are NOT computing devices for the general person who purchases them.
It reminds me the fallacy of calling smart-phones "supercomputers in one's pocket".
May be the ARM chip based devices are "computing devices" for companies like Samsung, Google, or some car makers but certainly not for general public.
"sure UNIX is nice, but you need a mainframe for REAL work"
"sure NT is nice, but you need a UNIX workstation for REAL work"
"sure mobile is nice, buy you need a windows PC for REAL work"
I crunched to inbox zero with my phone while commuting to work, while I'm typing this at my "real work computer"
I read that statement more like in terms of the freedom you're allowed to build and run applications for such devices. Mobile devices usually discourage the user to do this.

Even if we disregard how arbitrary that definition of "computing device" is, it's still a false proposition. Anyone can easily get a browser, a word processor and spreadheets on their mobile device or tablet (ARM). That's about as much computing as a significant chunk of the population requires.
I have debian chroot on my Android device which gives me Vim, GCC and javac out of the box.
But most of them are full of ARM chips fab'd by companies not named Intel.
