So a while back Hunter's Xbox 360 did a face plant. So I called up Microsoft. Much as I hate to say a kind word about Microsoft, they checked the serial number and said, yep, your unit is under warranty.
A couple of weeks ago, I took my Macbook into the shop to get the fan fixed. The tech called back to say, by the way, your case is cracked, and that's under warranty, so I'm ordering you a new case. Because according to Apple, that unit, with that serial number, is under warranty.
A month ago, Hunter's PS3 got the Red Screen of Death. Safe Mode does not recover. So I call up SONY, and they say they are "unable to populate a date of purchase," which is SONY for, "If you don't have the receipt, it's $156."
Gee, thanks a lot, SONY. It's nice that your unit is a Blu-Ray player and has wireless, except right now it isn't and it doesn't because it is broken. And even though it's under a year old, you won't fix it, because it's a gift, and it didn't come with a receipt.
It certainly would be very easy for SONY to have a database of serial numbers and when those units shipped. They probably do
have one. They just don't care enough about their consumers -- or they care too much about their
profit centers -- to use it.
