Initial testing of the Experience and Education packs has shown that many of the applications will work well on a umpc, but not all. For the ones that won't work well - the crossword puzzle for example - we are considering possible solutions as we recognize the content of these packs is useful.
As you pointed out, the Touch Pack was our first pack geared directly towards the umpc. Our team wants to continue offering value to our umpc customers, especally taking advantage of the form factor. It has not yet been decided if this value should be delieved through a pack or not.
