Well the main thing that's created a headache is that twice over the last 36 hours it has frozen up completely. Once I had to do a battery pull and the other time I waited it out and after about 5 minutes it restarted itself. Once I was attempting to use Choice Dialer, an app I use all the time. The other time it was just "waking up". I haven't had a problem with choice dialer since yesterday afternoon, so maybe it was a random thing, which is why I might not do anything. Both times it happened, my phone didn't appear to be too hot or anything along those lines, either.
Edit: The other thing that's not a real big deal, but just a bit of a nuisance when added with the freezes is that certain widgets keep popping up with "can't load" or whatever the message is, so I have to reload them, they work for a few hours, then it pops up again. My connection is strong wherever I go, otherwise that would be my first thought. If it just happened once, I also wouldn't give it much thought either. This has also become more of an issue just over the last couple of days.
