Yes. I upgraded to this friday and its been perfect ever since. The only differences from .148 I've noticed is the way apps open / close in a somewhat cooler way. And the glitch with song volume going to 0 from song to song seems to be fixed. So far, this is the best OS I've had on the phone.
I upgraded last night and thus far .151 seems to be more responsive than .148. Also, the app transition effect is cooler, and my free memory at any given time is almost twice what it was on .148 (average on .148 was 22MB, average thus far on .151 is ~40MB).
With just under 24 hours of use, this OS seems significantly better than .148 in performance. Stability is still under review.
