The only people that are claiming the "PC is dead" are the marketing agencies working for big corporations. LOL
I think a more nefarious angle of this is that with LESS computing power, and LESS user control, their dreaded black cloud can become a dominant force and make these big companies more money. Greed is a large element of what is driving the cloud crap.
I honestly think that is the agenda. Of course I don't like it one bit, I will NEVER accept the Cloud as they see it. Hopefully the general public will come to realize how potentially dangerous it is.
As for Windows 8 Metro being a monster hybrid, well that is EXACTLY what it is.
Worse yet is that Microsoft is FORCING you if you have Windows 8 to ALWAYS boot to metro at all times. You have NO choice.
How is that for satisfying the customer, it seems more like they are sticking it to them.
Oh and I am NOT going to stop using the term "metro" for ..uh the metro UI.
I think the only and REAL reason why they have decided they don't want to use it is that the reaction to the UI is so utterly negative that they HAD to drop it.
