What you describe sounds good and makes me want to try it as well in the future (there's stuff in OSX, mostly of the recently introduced sort, that really grinds my gears). Then again, I will probably still miss things like Spotlight, Quicklook, Mail.app, PDF print / cut / paste / manipulate with Preview + iWorks too much. How is Ubuntu coming along with such features nowadays? At least in Kubuntu I find that stuff still abysmal.
