What additional *performance* features are there? Please tell me... if we're talking about speed, the 9600 is the only difference. Even then, given most users' habits, the difference will not be substantial (save, perhaps, for gaming and/or heavy video editing).
Anyone who thinks that a MB is a "crapbook" clearly hasn't thought things through carefully enough (the whitebook is still an excellent computer). If I really cared about the 'pro' label, then I would have stayed with the MBP (duh). If anyone has insecurities, it's most definitely you (just look at your sig!).
As for the cost, well, prices are different here in Canada ($400 difference with the edu discount). So, that is a defunct argument and one that clearly does not apply to performance differentials. If you're going to go with a MBP, you might as well splurge for the 2.53Hgz model, IMO. And if you get the MB, you can easily buy an external monitor to offset the lower quality of the screen (and in my case, still save some money).
QED.
I had a feeling you would say you had a Pro or could of easily bought one. I was right. How original.
There is a huge performance upgrade between the 2. No point arguing. Enjoy your entry level Macbook and I will enjoy my Pro.
