more iphone activesync lacks

and I quote here

1. Spotlight does not include full-text search of mail messages. Although it’s nice to be able to search through everything on the iPhone, and even content on the Exchange server, you still have to remember the sender, subject, etc.
2. Battery life is poor with Exchange ActiveSync push and the new push notifications enabled. iPhone push battery life has been a problem for quite a while.
3. Still no notes and tasks sync (with Exchange). Although iPhone OS 3.0 does allow synchronization of notes with Apple Mail for Mac users, it does not support Exchange or Apple’s own MobileMe over-the-air services.
4. No public folder support.
