Is the current version of Messages beta stable enough to use day to day?
I am running Messages via Mountain Lion, but I believe that the application is functionaly identical to the Beta for Lion.

I have the following regular issues with it in day to day usage:


Badge counts are inconsistent, and it often says "1" regardless of reality
Icon Bounce - it bounces in the dock a lot as if something has happened, when nothing (that I can see) has
Slow syncing - when I have used iMessages on my phone, and then move to the desktop, it drip feeds the messages it needs to see to catch up really slowly, and you get a notification every 10 seconds or so for what can be a very long time if there is a lot to catch up on


Also, at least once (though this could have been a ML bug) it started using the wrong icon, showing a picture of a friend in place of my own avatar against my own messages.  Investigation showed the "me" card had been ammended in Contacts...
