How much better is Android 4.2 (Jelly Bean) than Android 4.0 (ICS)?


My current HTC is about a year old, and runs Android 4.0 Ice Cream Sandwich (ICS). I don't really need to replace it, but Christmas is coming up, and new phones have a tendency to show up in my stocking on Christmas day if I drop a few hints as to what I want. The new Nexus 4 looks pretty sweet running on Jelly Bean, but is it worth the upgrade? ICS was a pretty big improvement over Gingerbread; is Jelly Bean that much of an improvement over ICS? I seriously doubt my current phone will ever be upgraded OTA, so getting Jelly Bean means a new smartphone.

I haven't used it, but here's a list of what's new in 4.2. It might give you an idea if it's worth upgrading or not. If you don't need the new features, then I'd say skip it.

What’s New in Android 4.2 Jelly Bean

"Android 4.1, known as Jelly Bean, debuted only five months ago. But Google’s already back with 4.2, which will be called … Jelly Bean. But while the name remains the same and the overall user experience sees only minor tweaks, there are still plenty of changes you should know about. Android 4.2 is making its debut on Google’s new Nexus 4 smartphone and the Nexus 10 tablet, both of which begin shipping in November. But older Nexus devices — such as the Nexus 7 tablet, and the Galaxy Nexus and Nexus S phones — will get the update shortly thereafter.

So what can Nexus phone and tablet owners expect in Android 4.2? Here’s a rundown of our favorite new features."

Good timing! The day after you post your question there is a review of 4.2 on ars technica.  It's an improvement, but not as great of an improvement as the jump from 2.3 to 4.0 was. 

Here is the ars review:
