The $399 Everex CloudBook ultra mobile PC is supposedly in stock at WalMart.com, but Linux hardware builders ZaReason say they won't have any until the 29th. Cloud computing is central to the design and marketing of the CloudBook. As Everex puts it:
9 Inches, 2 pounds, 5 hours of battery life. Surf, email, blog, IM, Skype, compute. Cloud computing makes it simple and easy for everyone.
The CloudBook hardware is based on VIA's Nanobook design which is also used for Packard Bell's EasyNote XS (which runs Windows XP.) So the CloudBook has some relatively beefy features for an ultra mobile PC, such as a 30 GB hard drive and DVI out, but local storage and big screens are not high priorities in cloud computing so these features are buried in the technical specs.
Instead the gOS operating system gets top billing - an Ubuntu distro which Everex also uses for their very low budget desktop PCs. Cloud computing is at the heart of gOS, which features Google search right on the desktop. gOS's Mac-like user interface is a testament both to Apple's contributions to cloud computing and to the experience-oriented computing giant's missed opportunities.
I'm a proud XO adopter and love to show off my UMPC's amazing physical transformations, but I envy the ergonomic innovations of the CloudBook/Nanobook/EasyNote XS form factor. The simpler clamshell design has a wide gap between the screen and the keyboard so you can hold the CloudBook in one hand and punch keys with the other while standing up. The touchpad and mouse buttons are on the left and right sides where they can be thumb-controlled GameBoy-style, again allowing you to operate the laptop while supporting it's weight with your hands.
In my experience these are the ways you instinctively want to hold a laptop when it is not resting on a table: with one hand directly under the center of gravity or with both hands on opposite sides. I have experienced significant discomfort trying to find ways to use my 15" laptop while sprawled on a couch or the smaller XO while standing at a bus stop. I even found myself automatically trying to grip the larger laptop like a CloudBook, feeling for a finger grip behind the hinge.
Watch the ergonomics of this design in action.
