What do you think about Android 4.1.1 (Jelly Bean) on Nexus S?

I'm finding that ICS was the best performing version of Android on Nexus S.

Jelly Bean is slower on Nexus S compared to ICS.

Text input doesn't give you any punctuation suggestions like it did in ICS.

Notifications are similar to ICS except it gives more details but doesn't have full control as in Galaxy Nexus JB.

What other limitations you find in Nexus S with Android 4.1.1 (Jelly Bean) ?
