cosmetic defects on 3 macs I purchased

First I purchased a macbook. It arrived covered in scratches. Apple tells me to drive 200 miles to an Apple store to replace it. Next I buy a 24" iMac. It arrives with dust trapped behind the screen. Apple tells me to drive 200 miles to an Apple store to replace it. Last week I buy a 20" iMac, it arrives with a tear in the aluminum, leaving a dangerous sharp jagged edge. Apple first tells me sure, they'll replace it for a $150.00 restocking fee. I complain, hey, this is your fault, and they relent and agree to pick it up and send me a new one. Appriox. $5000 in 3 macs, all have cosmetic defects, 2 200 mile drives, and not so much as a "we're sorry" much less any compensation from Apple.
