HP's new 13" Folio just leaked on the blog Ritchie's Room, adding to the cacophony of Ultrabooks zooming around right now. The design isn't as much of a departure from Hp's current laptops, but it's just as slim and pretty as you'd expect an Ultrabook to be, and a little tougher, thanks to a rubberized base and sides.

The Folio will come with either a 1.4GHz Core i3 Sandy Bridge process or or a 1.6 Core i5 that can max out at 2.3GHz with Turbo Boost. It's also got a 128GB SSD and 4GB that is apparently expandable to 8GB. That would make the Folio the first expandable Ultrabook if it's true and not just a spec sheet flub. Overall, it looks like a solid little machine that should be out by late December. [Ritchie's Room via Verge]
