I was lucky to have had my device updated to Jelly Bean a few weeks back. It’s smoother, more responsive and I did notice some small fixes. One of the major differences with Jelly Bean is Google Now, which is similar to Siri but for Android. Voice commands for Android were available way before Apple introduced Siri but they weren’t as good. Seems tables have turned. I mostly use Google Now for power naps “Wake me up in an hour” is frequently used.
