Sorry for the really late reply to this one, but the answer is YES. Our policy is "No LearnPad left behind" and we make sure every new release works with every LearnPad, including the 10" LearnPad 1.
In some cases the older hardware or OS version won't support a particular feature, but it's rare. For instance, LP1 doesn't have a GPS for exact location reporting, but the location can still be guessed at from the network environment, so LP1 reports that instead.
