Gadget Madness brings to our attention a prototype sub-tablet PC called the A5 that is reminiscent of the Sony U50/U70, although not quite as nice looking. While the prototype "runs RISC OS under Windows XP," for most people the "Windows XP" part is all that is going to matter. An integrated 8.4-inch 800 by 600 pixel screen, 40GB hard drive, and detachable keyboard and touchpad round out the unit. Unfortunately, there's no real word on what class of processor it uses, information that is sure to become available if any OEMs decide to actually mass-produce the unit.
