I actually have it on mine due to a need for minimal downtime which precludes depot repair if offered, and I will take it in directly if anything goes wrong. Not everyone has 2 Apple Stores within a 20 minute drive. Anyway I wasn't thinking of Best Buy there. I was thinking specifically of OEMs.
I don't know if they still do it but from my experience Hewlett-Packard used to have THE BEST service ever. ( on their professional stuff )
I once bought a USED HP Omnibook. I sold later sold it to my boss for his daughter. She had a problem with it and he asked me if I could take a look at it. I determined the HDD was bad so I called HP to order a replacement.
The HP rep asked for the serial number, and I gave it to her.
She came back to inform me .... " It is still under warranty, FEDEX will be at your office tomorrow morning ( monday ) to pick it up. That thursday FEDAX came to my office to bring me the repaired Omnibook. "
This was a long time ago.
At that time you could go to a consumer store and buy an HP Pavillion for maybe $1,200. If you wanted an Omnibook ( new ) you had to have a in with that supply line and $3,500. HP would not allow consumer retailers to sell the Omnibook.
Also they were NETWORK CERTIFIED by Microsoft to run WinNT and that added to the cost.
ALL Omnibooks had a 36 month warranty with ON-SITE pickup.
if you had an HP service center in you area you could upgrade the warranty to get 24 HOUR turnaround at the service center.
