Ok guys, I'm sure you're all very tired about reading and writing posts about powerbooks...well, maybe not. So, I have a somewhat general but kinda specific question: I definitely want the 15 inch powerbook but can't quite decide. You have the one without the superdrive, with the airport extreme, with one gig, no-lit keyboard, and etc. Anyways, I just was wondering which Powerbook you all went for and why. Is the high memory speed important? Do you really like the superdrive? Backlit keyboard?? Thanks for helping...!
