It is too early to name anything special now. We'll see how much will be opened. At least it will be a bit easier to run own stuff on new DSP and use other hardware that Nokia decides to not to use for whatever reason. But still the 3d chip may remain closed (it is licenced from 3rd party). Also wi-fi chip in current tablets is not from TI and is closed too so there may be not improvement here.

What matters it that it proves that times are changing and companies like TI feel the pressure and see the importance of having things open. And due to domino effect it will sooner or later push others in same direction too.
