Thank you; you are obviously better able to articulate this subject than i.My short view: They try to abuse computers to sell them as entertainment devices.
We will be more and more entertained, more dumb in sum, the huge amount of information we get is more and more without quality. They try to move us buy the newest nonsense. A good keyword to start: Obsolescence

Never ever can a small device like a mobile phone or even netbook, smartphone, etc be an alternative to my Desktop PC. They are just another toys, for a huge amount of money, to be thrown away in 3 years.
