I posted earlier along the same lines, but I didn't get much of a response, so I'll make it simple: Should I get a 15" or 17" powerbook? I need it to run a music sequencer, like Digital Performer or Logic, but portability is a factor. I'd like to be able to carry it around so I can set up a studio anywhere, and also, y'know, to be able to enjoy the general go-anywhere-ness of a laptop. But, I wonder on the other hand whether that big beautiful screen will come in handy when I've got a couple dozen tracks and a video window to look at. Or, maybe the 15" screen is big enough (it's no slouch), and I should go for the more streamlined and svelte option. Is there anybody out there who has any experience with these kind of applications, or something like them, and can help me practically weigh the screen real estate/portability debate? Thanks very much.
