I recently upgraded to a mac pro from a 15" G4 Powerbook and so far I am very happy. I now have a need to be more mobile and I'm finding it difficult to choose between the MB and the MBP. Although I won't be doing any video editing or Photoshop work I do tend to have lots of applications running at the same time. Mail, iTunes, Safari, NNW, DevonThink, Filemaker, Office, Merlin, amongst others. I would also like to be able to run Parallels or Fusion without the machine slowing down too much. I'm confident that the MBP can handle this but not sure about the Macbook. My other main concern is the keyboard. Assuming I can get around the lack of some Pro features, particularly the express card slot. What do people think of the Macbook given my situation? Any help or insight would be greatly appreciated.
