>> "The most important enhancement is not even on the list: an iPad with several hundred apps is totally unwieldable. That should be fixed."

This isn't a problem very many people face. The average iPhone user only has 65 apps installed (Source:Flurry) (I don't know about the iPad but I guess it would be around the same). Apple typically doesn't cater to the needs of a minority.

With folders you should be able to get a very large number of apps on your iPad's first home screen. I think it's around 400 (20 folders x 20 apps per folder).
