I just learned that MCE Tech (www.mcetech.com) will be offering SuperDrive upgrade for older TiBooks. What is interesting is that their SuperDrive will be offering x2 speed DVD-R burning, while current Apple PowerBooks are only capable of only x1. Makes me wonder if Apple deliberately lowered the setting on the SuperDrive which is actually capable of faster burning. I do remember hearing a rumor about that, relating to how 17inch PowerBook's original spec suggested x2 DVD-R burning speed that was later changed to x1. Another thing I wonder is how Apple would feel about this. For one thing, this upgrade will be faster than Apple's. Second issue is that this upgrade is supposed to be iDVD compatible. Apple made a big deal about some plug-in while back that allowed iDVD to work with external DVD-R drive, which wasn't supposed to happen. Apple eventually forced the site to stop distributing the plug-in. They probably did this in order to have people by brand new Mac with SuperDrive if they wanted to use iDVD. So how would Apple react to this SuperDrive upgrade?
