The biggest limitation I can see for the Pre is that they are limiting apps to Javascript which is fine for certain things, but its interpreted and therefore a bigger battery life drain and order of magnitudes slower than native code access. Unless they release a proper SDK with low level access to the phones hardware then there will be serious limitations to what apps are able to be coded.
Going to limit any decent gaming apps and anything that wants 3D. I'm sure they'll get a C based SDK in the end, or they'll not be able to compete with Android or Apple.
