Hey everyone, I've got a first gen Macbook Pro, and was contemplating putting in the Superdrive from the current Macbook Pros that feature double layer burning. What is the model number of this drive, and does it have the same height and size characteristics as the Matshita UJ-857 that is currently in my laptop? Also, do you think it is worth doing that along with a HDD upgrade, or would it be more cost effective to just buy a new MBP? (I do a lot of audio work and music storage, so the Core 2 Duo and bigger HDD options would be of use to me). Let me know, thanks!
