Yes, just noticed that the 13" MB only has one audio in/out jack, unlike the 15" or 17", which have two. I also forgot about the IR port, which allows a remote. Here's an updated list of the differences:
- Illuminated Keyboard
- FW800 port
- Crack resistant aluminum case
- SD card slot
- 4 GB of RAM instead of 2GB on the MB
- IR port
- Battery level indicator
- Slightly lighter
- Thinner and sleeker
While I don't think the MBP is such a great deal either, for the price, it's a lot better than the MB, which, when maxed out, costs about the same as the MBP while lacking many of the above features.
I think Apple has dropped the ball a bit here. Some people who are looking to switch to Mac with an entry level Macbook may find this a bit too expensive and might not want to get a pro model either. If I were in this situation, I'd stick with a PC if I wasn't sure about switching.
If the MB were 100 dollars cheaper, I'm sure their margins would still me massive, and whatever they lose on margins would be made up for by increased volume and market share. Given that people tend to stick with Macs once they switch, any short term losses (if there are any) from a cheaper MB would be offset by having a larger base of long term customers.
