Another example is MotoBlur and Sense UI. Look at MotoBlur on a Backflip and see how horrible it is. Then look at how it has changed on the Droid X and how much less intrusive it is. Look at the progression of Sense from the DInc to the Desire HD. Manufacturers see the writing on the wall with Gingerbread and are doing what they can now to make their custom UIs less intrusive or for that matter widgety and selectable. Don't be surprised if Sense and MotoBlur become highly customizable widgets after Gingerbread goes mainstream.
