It’s been a couple of weeks since Dell first showed off the Inspiron Duo, and today we’ve gotten some more specifics on the device. The device is notable due to its unique notebook-to-tablet flipping mechanism.

Aside from its flip mechanics, the Duo has the distinction of being powered by a dual-core Intel Atom N550 processor, making it one of the first dual-core devices in its class. It also comes standard with 2GB of RAM and a Broadcom Crystal HD accelerator for graphics — if anyone has experience with this graphics chipset, please sound off in comments. It’s running Windows () 7 Home Premium, but given Dell’s penchant for customization, there might be options for other flavors of Windows 7 ().

The Dell Inspiron Duo will be available in the first week of December for $550 at its stock price. We’re actually rather intrigued by the device, so we’ll keep an eye on it and let you know how it performs when we get our hands on one.

T-Mobile just announced that Samsung’s Android-based tablet computer, the Galaxy Tab, will be available in T-Mobile stores on November 10.

After Verizon and Sprint, T-Mobile is the third major U.S. carrier to reveal the launch date for the Galaxy Tab, and — unless AT&T spoils it for them — T-Mobile customers will get the chance to buy the device one day before Verizon customers and four days before Sprint customers.

In the announcement, T-Mobile mentions its fast HSPA+ mobile broadband network, which should go hand-in-hand with Galaxy Tab’s 3G chip, but it doesn’t mention the price. The mystery of Galaxy Tab is nearly solved, but until we hear from AT&T and learn the price for the device from T-Mobile, the puzzle won’t be complete.
