writes "Amazon has quietly revoked the $50 rebate for Mac OS X 10.2 it was supposedly offering through September 3. The rebate form was updated to reflect this a few hours later. While theories as to why abound (including supposed involvement from Apple), some have reasonably pointed out that Amazon may not have expected as voluminous a response as they got, making the rebate a potentially major cash loss had it continued at that volume. People who already placed their orders should probably contact Amazon, while the rest of us can simply continue hoping Apple will offer its own 'rebate'."
I think maybe it was a mistake; the rebate form I saw originally never had Mac OS X 10.2 on it.
