With rumors of an Apple iPad mini in the air, Samsung on Tuesday unveiled its own 7-inch tablet, the Galaxy Tab.

The rumors are now reality: Samsung on Tuesday showed the world its first glimpse of the Samsung Galaxy Tab, the company's new 7-inch tablet.

Samsung posted a teaser video on its Web site; Samsung Mobile will release more information about the Galaxy Tab on September 2 in advance of IFA Berlin 2010. Meanwhile, speculation builds that Apple will also of the at a September event.

The details on the Galaxy Tab are thin, but here's what we know thus far. The Tab will run on Android 2.2 and feature full Web-browsing and video calling. The short clip also implied that the Galaxy Tab will sport an HD screen for video, Flash support (something it seems the iPad will never have), support for e-books, possible GPS navigation, and PC linking. The few shots of the screen's keyboard look promising, as do the brief flashes of the built-in apps. The device itself is black, with a few buttons below the touch display and the Samsung logo up top. There's no word on pricing yet.

Meanwhile, the Apple iPod event that has become a September tradition in San Francisco has yet to be announced. The Web was recently abuzz with also being announced alongside the new iPod crop, but Apple rarely shows off new products ahead of events, and since there has been no official word from the Apple camp, all we can do is speculate.

One thing is certain: if and when a new iPad mini hits the scene, it will have, arguably, its first serious competitor in the Samsung Galaxy tab, though and have released tablets with varying degrees of success.
