Chrome notebooks coming
You may have heard of the Google Chrome notebooks: They will feature only a web browser (Chrome, of course). Everything you do on the machine will be done on the Net and with web apps. If you don't have a Net connection, the machine is a doorstop. There's no access to local files and not other apps or system on the machine.
Rumors are now that the machines will be paid by subscription. You don't own them, you rent them cheaply.
I'll do my thing again: isn't it amazing that in the nineties, notebooks were luxury products which cost three times the price of a desktop machine, and still were much slower and had cramped screens. In the noughties, they pretty much replaced desktops for many. (Even for many people who didn't need the mobility, which I don't really understand.) And apparently in the tens, they will be virtually disposable, to be replaced like the cardboard cylinder in a roll of TP.
