Nokia has taken a page from Android's book with its homescreen, which is heavily widgetized and customizable, to a point. It has three pages, each of which is wide enough for four items--and only four items. Widgets have to be four items wide, and individual items (like, say, apps) can only be added in groups of four. Bizarrely, you can't move widgets or apps: You have to delete them, and then add them again, which involves a lot of scrolling through lists. So if you want to switch the locations of two widgets, you have to delete both of them, then add them both again in the right order.
