Always Innovating's Smart Book breaks the traditional netbook into pieces. A touchscreen VoIP phone, a tablet, and a keyboard. Use them apart, or combine them into a full-powered device when you have to. Buy one device, carry what you need.
The Always Innovating Touch Book does something I've never seen from a netbook: it has a fully detachable keyboard dock and transforms from a standard looking 8.9-inch netbook, to a stand-alone tablet.
