Well, I think the ipad style of app is intriguing--they differ from a current desktop app in a few significant ways:
1. There's no notion of save.
2. There's no notion of quit.
3. There's no notion of filesystem.
Those are all interesting tweaks.
Having the app save things automatically and always present you with the most up-to-date version of your document is kind of cool actually. But, you say, "I don't want it to save my document sometimes--what if I want to experiment and then throw away the changes?" I think that is where the new "versions" feature fits in. It seems designed to give people exactly that. I suspect that ⌘S will change from "Save" to "Snapshot".
Having the app suspend itself, save its state and unload at the appropriate time is interesting too. It gives the app a sense of persistence that doesn't exist in most desktop apps currently. I've already subconsciously switched to this style of thinking. I like my Firefox set up to restore the windows from last time. I do a similar thing with my Emacs so that all my buffers get saved and restored (emacs-desktop).
I think I'd have a hard time letting go of my filesystem. I don't see anything in Lion that seems to indicate they are moving that way. But I kind of understand it. It'll probably start moving that direction eventually. But who knows.
