I missed this comment, sorry for the late reply. A warranty system guarantees for free repairs or replacements but doesn't guarantee for a reliable product.

Plus choosing a $1000 for a 10-year warranty would be a very bad deal, since $500 guarantees you 5-year product, additional working time or ability to sell and repurchase of an improved version of a product. Minus could be inflation or less reliable product in the future.
