I was browsing on Amazon.com today and noticed a number of Rev C iBooks and Powerbooks with $150 rebates. Rebate Link I have no idea why there are rebates, though ... maybe they're trying to compete with the Cram and Jam rebates? The only other time I've seen such discounts on Powerbooks / iBooks is right after a product upgrade. Anyway, I'm not necessarily endorsing Amazon.com, just passing this along. It seems like a good deal if you're in one of the states where they don't charge tax.
