Question about Nikon warranty transfer between owners

I wonder why camera companies can't have something customer friendly like this for their higher end cameras ....

"Dell makes it easy to transfer the warranty and ownership of certain Dell products from one owner to another owner and from one country to another. The transfer process can take up to 10 business days (domestic transfer) and up to 15 business days (international transfer)."

After all, these cameras cost more than many computers.
