The next MacBook Pro might not be slim like a MacBook Air, a report today suggests that instead it may gain a bigger but longer lasting battery.

The MacBook Pro may still lose its optical drive, however. Losing the CD/DVD drive could free up space large enough for two 2.5in hard drives (or SSD drives).

With this extra space, Apple could include a large capacity traditional hard drive, as well as a SSD drive that could be used as a boot volume.

The Slashdot report that is promoting the idea is based on a thread on Reddit, which doesn’t necessarily lend it much credit. However, we think that it's an interesting idea and it shows the value in the space taken up by the optical drive that has (we think) become quite redundant now that the Mac App Store has taken off.
