if nokias MeeGo does not have customizable home screens dont be surprised.
at LeWeb it was said Android & symbian was one way with its homescreens, iOS is another where you always start from the front door i.e home button and WP7 was an interesting and new way, but Nokias MeeGo will be something different.
I'm starting to think in terms of Panels what Collect and Gather your Data from the web and on device Media and stuff, something along the lines and little like Tablet MeeGo pre-alpha video b/c he talked about not needing to have you head down looking at device for long periods and then went on to talk about data gathering.
