David Pogue said the touch screen keyboard in landscape mode was "barely usable".
Yes there is a optional keyboard stand, but it requires a desk.
Yes likely the optional Bluetooth keyboard will work with the iPad, but now your supporting two devices on your lap or other uneven surface.
Yes there is the plain stand, but one has to set that on a desk or coffee table and then the bluetooth keyboard in their lap.

Edit: I noticed later that there are less keys on the iPad keyboard, giving it the appearance it was tiny. The size of the keys appear to be the similar.

Reason iPad's keyboard is smaller as it has less keys, the key size seems to be about the same as normal.
