10.7.3 booted up fine after the 15 - 20 minutes of safe mode updating.
I did a google search for 10.7.3 and apparently, it came out on February 1st, not today, like I thought.. Although I find it rather interesting that 4 days goes by without an update notification. It's possible that Apple pulled the update, made fixes, and then relaunched days later, like today.
Also within the Google search was evidence that others (many others) have had nothing but problems with the 10.7.3 update, and that user who updating manually had better results. See this article. Glad I didn't get the update right away!
Again, it seems, thus so far, that Apple OS X Lion 10.7.3, as of February 5 @ 6:27 am works fine. However, I don't have enough evidence to say that the 10.7.2 glitches, slowness, and stability are any better.
