I respectfully dissent on a few points:

1) There is no way a tablet matches up to the wide screen, full-size keyboard, and large hard drive of my desktop, or even my laptop.

2) Tablets are pretty much closed systems. Forget about installing Linux or plugging in a better video card. In addition, there is no upgrade path. Buy the expensive tablet one year, and it will be obsolete, unsupported, and unupgradable the next. (See first-generation iPad.)

3) You mention using the same device for work and home. Not unless there is a radical change in the law, I don't. I am very happy with my employer, but no employer is going to sink its legal teeth into my iPhone, thus opening up access to all my personal data. And I don't see any way that corporations are going to give up their near-absolute right to all data on "their" machines. So I will buy and use and pay for my own iPhone, thank you very much; our corporate masters can keep their grubby hands off it.

4) In sum, I don't have a tablet; I don't need a tablet, and I don't want a tablet. As for a future in which we are all tablet zombies, it is not a future I relish.
