My Pre2 (EU) has definitely gotten more sluggish now... (just installed the update, will see what happens after a few hours).
What bugs me is that, in some places, the UI is not as beautiful and crisp as it was before. The Phone->Preferences & Accounts is an example... where you'll find:
- The labels and sliders don't line-up at the center of their respective rows.
- Several labels themselves don't line-up correctly at the left margins.
- There are awkward separator lines in many places.
- Then, the list rows don't have equal heights. (e.g., between Manual Settings and Edit Network Settings)
It's a shoddy job, HP! You messed-up what Palm did right the first time.
It's going to be a looooooong winter... waiting for this to be fixed.
I'm seriously considering going back to 2.1.0.
