You're most likely to find this service if the company in question is dealing with
1) Innovators/Early Adopters (their goodwill, word of mouth etc. is highly desired as is the feedback you can get)
2) High end stuff that is bought because it is high end (some level of service similar to this is standard for Porsche etc...also a good chance to sell you a new car :P)
3) Equipment that professionals use, it's basically an implicit insurance policy (cameras, lab equipment)
Porsche is actually known for NOT being helpful to owners when they screw up. They deny fault for many major recall worthy issues, go visit some Porsche forums and see for yourself.
