One of the coolest products for digital cameras that I have played with in a long time is the Eye-Fi line of Wi-Fi equipped memory cards. These little SD cards can automatically upload images you take to Facebook without you having to do any work.

Eye-Fi has announced that the manager software has been updated and will allow all Eye-Fi cards to work without any issues with the new Mac OS Snow Leopard. The company is offering its latest SD card, the Eye-Fi Geo for $59 via the Apple store and at other online retailers.

Check it out. Amazon is now accepting pre-orders for Mac OS X 10.6 otherwise known as Snow Leopard. It’s listed for September at $29. The Five-user family pack will cost you $49, Server version is $499, and you can bundle a single or five-user pack with iWork and iLife for $169 and $229.

You shouldn’t have any trouble getting a copy of the OS, but if it makes you feel safe and secure to get in line now, all it takes is your credit card and a virtual trip to Amazon.

Apple has reportedly been working on this new interface since day one, even though publicly claiming that Snow Leopard would be more about performance and stability enhancements than sweeping feature changes. Even so AppleInsider claims that an upcoming 10.6 developer beta could feature a new UI codnamed “marble.”

Apparently it would be sleeker than the current look, and there’s some speculation that the new scrollbars in iTunes and iPhoto offer a glimpse into the future, along with the mockup of the new QuickTime X player above.
