iFixIt has published a teardown guide for the MacBook Pro 13inch unibody which compares it to the MacBook Unibody throughout the teardown.

Some comparisons to the MacBook Unibody:
- No access door for the battery on the bottom.
- The addition of an SD card slot (and the omission of digital/mic port) is readily apparent.
- FireWire is back!
- Computer lock is now on the other side.
- The SD card sticks out almost .5"! This is a cheeseball design for a MacBook "Pro" if you ask us.

7-hour battery specifications:
- Model A1322
- 10.95V
- 60Wh
- "This battery contains no mercury (Hg)."
