Hehe, read some of the comments. Some of them make very interesting and valid points, despite the article being mistitled.
Just a few that caught my attention....
I especially liked the ones regarding the death of efficient program coding in today's era of quad-core chips. Even a few stupid widgets require an amazing amount of RAM just to run in the background.
Also, there is the issue of boot times. Maybe solid state hard disks will throw the old slow boot times out the window?
Also, keyboards and mice need to change. Period. They are simply not the best way for the human body to input information (just think about carpal tunnel). I think many would agree that drawing a circle with a pen-and-paper is much easier than drawing a circle with a mouse. Also, one can write a mathematical formula in a few seconds, whereas it would take a minute or 2 with MS Equation Editor.
Anyway, just regurgitating some of the gripes I saw and adding a few of my own thoughts
