There is no doubt that Apple was impressed when they were shown the expected performance of Conroe - and this is likely one of the reasons why they picked Intel as their new CPU provider for their machine line-up. However, it looks as if Apple is going to have very distinct boundaries with the Intel CPUs. With the old SKUs of Apple products (iBook, Powerbook, Power Mac) they used the same CPUs across the board, just at the different clock frequencies. Apple are using Yonah within the iMac, MacBook Pro and the Mac Mini - as they have already shown.
