I think I am leaning my interest on the smaller 12″ model. I know I can live without FireWire 800, can add the SuperDrive and the 867MHz G4 is fast enough for my needs considering I have been very satisfied with my original 500Mhz model for almost 2 years. The real question is how readable I would find the screen. The resolution is what I am used to, but now on a much smaller screen.
I know I would absolutely love the 17″ model, but am concerned about the size in my bag and having to carry the “extra” weight.
I guess it really does not matter unless I can get my office to agree it is time to upgrade… 😉
