I currently own a 2.2 GHz Core 2 Duo 15" MacBook Pro from August 2007. I am thinking of selling it and buying a new MacBook and a 24" Apple Cinema Display. Part of me would like a smaller computer since I travel for work everyday of the work week. I did not buy the MacBook a few years ago because I did not like the Black or White MacBooks, but since Apple offers aluminum models, now I have an option to go with a smaller computer. My only concern would be when I am at different work locations. I can't quite tell what a 13.3" screen will look and feel like. I only know what my 15" MB Pro feels like. Does anybody have any experience in moving down from the 15" PB or MB Pro to a MB? Did you notice the screen difference? Also, I am wondering how it feels to carry the MB with you in a computer bag. Does the 1 lb less weight make a difference? I don't do graphics work or use my computer for gaming but mostly for office docs, spreadsheets, presentations, and email. At home, I plan on using the Cinema display so size won't make a difference there.
