Ok. We can assume you will be paying $1000 more for the MB Pro, so what do you think the new models will have that the current refresh of Mac Books doesn't have. Will it be worth the price difference? GO!
The rumoired MBP should have LCD lit screens which is a pretty major battery saver. They will likely ship with Santa Rosa so will support more than the current 3gb memory. MB only can support 2. So memory capacity is your primary driver.
On the downside to the MBP, the MB can stand uncareful handling much better and the plastic case is better for wireless reception, and they are far less money. They are an outstanding value IMHO.
MBP on the other hand does have larger and nicer screens including a 17" option, can have FW 800 instead of mere 400, full DVI plug instead of cheater plug with a dongle to convert anything you really need. MBP have bigger batteries, and look cooler.
So it has to do with your need for many or large programs, how you handle your portable (every day portability or occasional portability).
On a feature per dollar basis the MB wins hands down. But it is always those special features, if you need them, like ExpressCard34 slot, or backlit keyboard, that can sway the switch to MBP and eliminate the option.
