It is a silly comment, and while he is correct in pointing out the growing importance of mobiles, the idea that office workers, graphics designers, and so on, will be working on a 3-inch screen and keyboard is .... ridiculous.
We may get some virtual tech going in a few decades, using Wii-style interaction or even brain-controlled, but it won't be anytime soon.
That's a ridiculous statement. I don't have a smart phone, and have no intentions of getting one. I can see using a smart phone as a phone, and as a PIM, but to use the internet or do email on one is an exercise in frustration. The screens are simple WAY too small to use regularly.
I love technology, but I'll live without the internet before I'd give up my dual 23" monitors. Progress requires change, but not all change is progress.
If that is the only option in the future, i am going to Linux and keep my files and my OS on my computer. Otherwise i wont use computer anymore so they can shovel their idea of Cloud Computing up to their ass
I can see it for gaming too - eventually. Look at the PC and console games of 10 years ago as compared to the hardware, then realize how many of these are playable on battery-powered handhelds today. Big monitors are nice but with 3D goggles rapidly improving there isn't a whole lot of reason for a desktop. The remaining limitation are input devices like keyboards but with motion sensing improvements even that could go away eventually.
Designers, CADers, Developers, Artists, Researchers, Gamers, etc. all have in common a need for powerful hardware to run their specific systems on, of course to check mail and wordpress you can do it on whatever mobile platform you've got, to get real work done, you need raw power.
This kind of thing is just self-serving propoganda.
For many users now a good laptop can replace their desktop computer. I even thought about it for my home use but decided I wasn't quite there and instead built a new desktop computer and bought a new monitor. In my business use anything less than the most powerful box I can build just wouldn't work. (OK, I'm a little behind now with a dual core at 3.8GHz and dual 22" monitors, but in another 18 months I can build a new machine.)
