Apple’s been pretty skimpy on licensing the MagSafe power connector to allow people to build external backup batteries. It would be nice if Apple would loosen the restrictions on MagSafe while it’s preventing people from swapping batteries.
I have two concerns about the new MacBook Pro. First, there are reports that the Mini DisplayPort to Dual-Link DVI Adapter doesn’t work very well. Second, it appears that the hard drive is not easily replaceable. This was my favorite new feature with the 15-inch unibody MacBook Pros. Removable hard drives provide more control over my data (especially if a repair is needed) and more storage options. Apple offers a 320 GB hard drive or a 256 GB SSD drive for $900 extra. I’d rather put in a 500 GB drive or a 256 GB SSD drive for $465, plus have the flexibility to upgrade as storage technology improves.
Update (2009-01-07): According to Macworld, the hard drive is user-replaceable, although not as easily as with the 15-inch. You just have to remove eight screws on the bottom panel, and this does not void the warranty.
