Yeah I know about their extended warranty; then their responsiveness is obviously due to the extended warranty, not any comparative admission of liability.
As to "Dell support has flown a repair guy to my place with spare hardware pieces ". You don't know that he wasn't already planning to fly to your area for 5+ other customers anyway. Also it's a less impressive story if you live in a heavily tech area than if you live in the Ozarks. Flights can often be cheaper than driving, and the rep has less dead/travel time and can service other customers or whatever.
I looked at Dell extended warranties before (can be ~about as expensive as the machine itself, over 3yrs) and figured that if you're buying with your own money, you can do better with due diligence on which specific year-models are/aren't reliable and what each component costs to replace, also couple that with a selective backup strategy. As long as you're not too remote.

I can tell you that wasn't the case because it was a small town that had a small airport. And they sent the guy next-day from my report. He told me he just flew for my issue and was returning on the same day.
If it was some large city or capital, they probably wouldn't have needed to fly the tech guy anyway. Someone would have probably been available nearby.
As for the price, perhaps it changes for different hardware, but for customer PCs you can see for yourself, it's around ~$45 per year. Which was free for me because of promo.
Just try to buy a desktop machine and you'll see it as an option.

The important part: "On-location repairs, by Dell certified technicians, after remote diagnosis (1-2 business days)".
There's no special business contract or paperwork involved.
And you can get it for free in promos. Like it did.
