I am hoping that the new ibook/macbook will be core duo, I think solo core would be a mistake. Hopefully the lineup will look something like this: Current Intel Core Duo Chips: T2600 2.16 GHz 667 MHz 31W (Future iMac / Macbook Pro) T2500 2.0 GHz 667 MHz 31W (iMac / Macbook Pro 17"?) T2400 1.83 GHz 667 MHz 31W (Macbook Pro / iMac) T2300 1.66 GHz 667 MHz 31W (Macbook Pro) L2400 1.66 GHz 667 MHz 15W (iBook/Macbook? 13.3") L2300 1.50 GHz 667 MHz 15W (iBook/Macbook? 10" / MacTablet) Or maybe an option of either solo or duo?!? What do you think?
