Apple Bought iSlate.com domain — Perhaps for a Tablet rumored lately?

Clever online sleuthing over the weekend led to the discovery of iSlate.com, a domain Apple purchased in 2007. Could the company’s rumored tablet device be called the iSlate?
The website is currently inactive, but according to information Apple could be reserving the domain for a tablet product, which is rumored for a January 2010 announcement.
The “Whois” record of iSlate.com provides solid evidence that Apple bought the domain in 2007 and subsequently transferred the address to MarkMonitor.com, a registrar that handles domain registrations for several companies, including Apple. The purpose of the move is presumably to help obscure products prior to release.
