Online auction sites, such as eBay, have hundreds of listings for iPad-themed domain names. Some web addresses can be snapped up for around $100, while others are listed for considerably more.
But the business is a contentious one, with some domain name speculators falling foul of trademark laws put in place to prevent cybersquatting or name-jacking, the process by which individuals buy the website address of a well-known company or individual, and then sell it back to that person or organisation for many times what they originally paid for the domain.
It's all a bit sad that a good decade+ into the evolution of the domain name system a) the big players (product developers, manufacturers, brand cos) still don't see this coming and pre-sweep the decks (register) of "close/relevant domains"; b) there still are/may be entities willing to help monetize such domains; and, c) despite fairly widespread knowledge of trademark so many people are willing to play the game. :(
