I think a desktop OS designed around 13"+ displays with keyboards and mice/trackpads running on a 10" tablet with fingers for input is a prime example of "a fool and his money are soon parted adage"
I wonder how many tablets have been sold since tablets were first introduced. It seems like Apple will outsell all tablet sales with it's iPad in a very, very short timeframe. I think we'll see Android-based tablets as the most profitable competitors to the iPad, with MS making a tablet version of their Windows Phone 7 Series OS which HP will surely jump on. A desktop OS is just foolish for that device type and size [and use].
