Dell has just made official its Inspiron Duo tablet netbook hybrid after news yesterday that it will be rolling out sometime in the near future. As expected, its unique 10-inch display which can swivel in different directions will certainly make it a novel purchase for just about anybody, while a custom layer on top of Windows 7 is capable of delivering access to media, the web and an iBooks-style e-reading app in a different manner. You won't find standard fare netbook specs underneath the hood with a dual-core Intel Atom 1.5GHz processor aided by 2GB RAM and a Broadcom Crystal HD accelerator that handles both full HD video and Flash with aplomb. Expect the Dell Inspiron Duo to ship in the first week of December for $549 a pop, although you can up the performance ante with a JBL dock bundle that sees the final sticker price touch $649.
