Yes this is a refreshing change, although I'd prefer dailies and utilities to be included in the power point pool.I really like the fact that they have finaly broken the power structure for the psion. It helps answer one of the most common complaints about 4e, i.e. that all the class feel the same.
Too bad they did not venture earlier in that area. I can see Wizards as having a few at wills, no encounters and almost all dailies and the reverse for fighters (mostly at wills and perhaps no daily) to really bring back the flavor of the earlier edition for these classes.
The real problem is, as implied in your 2nd point, that there is no logical reason why the psion (rather than say, martial classes) should have this kind of flexibility.
So for me, this is too little, too late.
