That word "unlikely" is rather worrying. I prefer "never".

I think that a company should publicise to its customers any shortcomings of their product that may affect them. It is surely the right thing to do. I just dont think you should pat people on the back for doing the right thing as if it is so wonderful - it is to be expected, in deed it is required.

If someone passes me in the street without pulling out a gun and shooting me, I dont approach them and say "gee thanks for not killing me - your a real pal - let me buy you a drink".

If Intel have done the right thing, thats good, but we shouldnt applaud them for it as if they are doing us a big favour by not lying to us. Thats my point.

I said slowed down, not stopped. Suppose one day they will be able to design and build new cpus on a weekly basis - would you like that? Pace of change can be both too fast or too slow. I like it when its just right (like in the Goldilocks story). I think a new generation of cpu's almost every year is too fast. But Im not advocating, as you seem to be suggesting, that progress is brought to a complete halt.

Except when you want to add in some kind of upgrade, like new memory to a motherboard, and find out its no longer available (as with my Pentium 4 m/b that uses RDRAM). Or when you want to move your ultra expensive AGP graphics card over to your new motherboard but find there is no AGP slot.

Sure if you never do an upgrade, then thats ok. But how often is that the real world situation? It never works for me.

So it would seem.

But perhaps if they slowed things down, they might get closer to it. Who knows?
