Wintel has done a desastrous job. It has perpetuated and cemented an insanely braindead way of doing things (not even inventing it: that blame goes to Big Blue), and yet people praise it for all the innovation they introduced. Bah, humbug. I can only hope the stalled progress will suddenly give to a breathtaking wave of innovation. All the ideas are there already. It is just nobody is willing to take the risks, since new technologies are expensive.

I think Merced architecture is stale already well before it has become available. The Sony Playstation 2 graphics synthesizer seems to be the only truly innovative hardware design I am currently aware of. The Xilinx people need some watching, as well.

There is no need to go dedicated. If there are hundreds or thousands identical CPUs in each desktop there is sufficient horsepower to do anything in software. God, we can do embedded RAM now. Nonvolatile core is a the threshold of viability, including for reconfigurable logic purposes. Let's dump code bloat and go WSI. There is a lot of silicon real estate out there on these 300 mm wafers. And quantitive yield can do wonders to prices.
