> There are some applications that have a very dense UI because there's simply alot of functionality that the program handles (think of a video editor, an IDE, etc). Trying to slim down those applications to make them reactive so that they will scale onto a phone or tablet just seems silly

And beyond that, platforms have affordances which you should want to leverage. A smartphone has a very direct and tactile interaction model, but my computer pairs an extremely precise pointing mechanism with a good way to input oodles of text and chord shortcuts.
