I miss the talents, in a way, but we got FAR more power points to compensate, enough that you could replace every old talent with a level 1 power and still come out ahead on spells/day. Unfortunately, the loss in powers known is a bit bigger of a deal, and many of the talents that were appropriate as a level 0 power (detect psionics, for instance) just feel underpowered as a level 1 power now. So, Psions tend to be missing a bit of low-level utility now.
The only change I'd make is to give more powers known at 1st level. They really don't need more powers/day.
