Eh, last I heard was that the current beta was really buggy (can't log in sometimes and such). Also comes with a ton of "crapware" (Diff AOL crap, Viewpoint, Plaxo, etc). Beta 0.88 worked ok for me, but that was the last that I tested. It's up to 1.1 now or something.
Another thing: The installer is just a download utility, you have to download the "real" installer from the one AIM gives you. Kinda strange, don't you think?
At any rate, if you decide to grab a copy of AIM Triton, be sure you get AIM Ad Hack
for Triton, and ViewpointKiller 1.05
. Those two will get a lot of junk off of your system if you download Triton.
