I absolutely love updates, but the new iPhone app feels like a big F U to power users. They're de-emphasizing direct messages by putting them a level down in the "Me" tab and switching accounts if you have multiple is found in the same place.
Also, not a fan of the wasted space on the sides of the tweet feed. However, the new web design looks great.
