MCE Tech <http://www.powerbook1.com/> says it will be offering a Superdrive upgrade for 667 TiBooks (like mine.) I bought my 667 before the combo drive was available and have not yet upgraded. MCE wants $499 to install the Superdrive, will keep my old drive, and requires that I ship my Tibook to them for the work. Does anyone know which drive Apple uses and if it is available for purchase? MCE says the install is difficult. Does this mean it requires more than Torx e.g. special tools? Bill Beecham
