Good points and I agree the assembly of a processor will not be as simple and easy as we may hope. But, it will no doubt be quicker to build 4 and 5 than 3 because they have done it before. Any hangups encountered in the assembly of 3 will no doubt be accounted for in future processors. The fact they spent so much money on clones of number 3 (4 and 5), it makes me feel that they are very confident in the design. I can't wait to see what it can do!
