The one neat thing it does is keep track of the messages you sent. Say we have a message and I close the window, aim by default will keep the prior messages in the window in memory, even if you close it.

Other then that, nothing else blew up my skirt regarding it, just more gui crap and sluggish.

If I think of any other pro's I will let you know. I have had it for like 4 months now, so I am kind of use to it now and forget or overlook the differences between the old and new version.
