Motion computing CL900 is not yet launched. It is due in the next 3 months. Motion have announced a price of under USD$900. Its pretty much a replacement for the aging LS800. It has a number of advantages over an ipad. Its printer support is better, being a Windows 7 device it will run Jeppview & Flitedeck as well as other flight planning software such as Command Flight Planner. The Jepp software has moving map support so a proper GPS engine can be used (As opposed to the Apple "assisted GPS"). Given Motion's history with the " view anywhere" screen technology, it may have better daylight visibility than ipad.
