One thing I hate is the Contacts is now with a white background that doesn't flow well with the stock dialer and messaging app.
I lost the ability to see messages on my car's multifunction display. It worked great with ICS, but not at all with JB. I'm pretty annoyed about this, as this was one of the reasons I bought the handset.
Although I know I can revert back to ICS, I shouldn't have to. I'm going to call Verizon and ask them what they're going to do to resolve this. I've had the phone a little over two weeks.
Also, it is laggy for me. I did the hard reset; it had absolutely no impact. I'm very surprised some of this isn't caught during the "soak tests." It tells me that either Motorola doesn't take the feedback from the soak testers (except for major issues), or the soak testers only participate because they want to play with a new release.
I am interested to see what response you get from Verizon. The problem with the soak test was they did it during the week for only 3 days then immediately following was the push from Verizon. I think the soak test should be longer with a weekend included. I don't think the purpose of this soak test was to fix bugs, but to make sure the update works and report bugs.
