I'm serious: about 80% of my day is meeting with real people in the real world. Mobile phones haven't changed that.
The other 20% of my day is sitting at my desk creating original work product (mathematical models and thoughtful memoranda) or reviewing the work product of others. Mobile phones haven't changed that, either.
No doubt the drought in PC sales is real and permanent. But I wonder how much of that is because people just don't need to keep their laptops up to date in the age of great cloud services.
As for entertainment though, are you watching Youtube extensively on your desktop?
There already is a relatively mobile tablet/desktop hybrid that works pretty great for both consumption and getting work done. It's called a laptop.
> As for entertainment though, are you watching Youtube extensively on your desktop?
Yes. I have a phone, a tablet, a desktop, and a laptop. The tablet is pretty much only used for netflix and textbooks, and the phone is for travelling. The tablet is absolutely worthless for browsing, coding, writing, or gaming; and the phone is only saved by the form factor. If I had (the space for) a TV then the tablet would be a completely unjustifiable purchase.
And yes, mobile devices have taken away entertainment share from the desktop as well as televisions.
I don't count time I spend out and about on my mobile, since that isn't time I was going to spend on my desktop anyway. (And I don't think having the option of going outside with a mobile has changed how often I do so.)
Plus, Intel provides almost all laptop chips, and I'm guessing most businesses still have either a desktop or a laptop per person, which will still get upgraded every so often. I doubt workers are going to be using iPads for data entry, although I suppose you never know.
None, since I don't want to have (and don't have or own) a portable surveillance and tracking device (also called mobile phone) in my pocket.
