I'm in the market for an older laptop, but don't really know the difference between all of them. I only need the machine for portability and internet/WP. I'd like it to be able to run OS X. All of my high end stuff I can do on my G5. Really, I just want a machine I can use at work instead of this Dell piece they have here. lol So I've primarily been looking at the Clamshell line, but how do they compare to the Powerbooks from around then? (Wallstreet, Pizmo, Lombard etc...) I've actually seen better prices on those. Are they any good? What is a good price for some of these machines? (avg. I realize each machine is different) Thanks!
