Amazon's tablet rumors took another turn on Tuesday, when it was suggested that the company has registered KindleAir.com.

The Kindleair.com site currently redirects to DomainTools.com, where the domain itself is registered to MarkMonitor.com. That's the same registrar that also registered kindlesocialnetwork.com and kindlesocialnetworking.com, which followed social networking additions to the Amazon site, reported Fusible.com.

MarkMonitor specializes in domain management, among other services, including "active and defensive" domains, which the new socially-oriented domains could encompass.

regarding Amazon's possible tablet. So far, Amazon has remained mum: Thomas Szkutak, Amazon's chief financial officer, was asked about Amazon's tablet plans during the company's July earnings call.

"We have a longstanding practice of not talking about what we might or might not do, and so I can't help you with that question," Szkutak said, without denying that Amazon was indeed building a tablet.

If nothing else, the KindleAir domain would suggest three things: one, that Amazon was designing the thinnest, lightest, tablet on the market, in order to compete with Apple; two, if it did use the term "Air" to describe it, it almost certainly would be facing a trademark or copyright infringement suit from Apple; and three, that the term "Air" could also be used to imply how content would be delivered to the tablet, i.e. over the airwaves.

Amazon has already been successful in giving away MP3s on a daily basis for free; since March, Amazon has done the same with its Android App Store. Every day, users can visit the store and download an app that users would otherwise have to pay for for free.

Analyst Tim Bajarin also suggests that Amazon might also seek to use low-cost parts to undercut the market, essentially selling the tablet below cost to win market share.

In July, a new report from Taiwan-based IT wire DigiTimes said that Amazon has contracted with Kindle assembler Foxconn to put together 10.1-inch tablets for a release date sometime in 2012, while Quanta Computer is now shipping a 7-inch tablet to the online retailer.
