Funny, I switched to GA...Pidgin, because Trillian would always crash on me, the IRC never worked for more than 2 minutes, file transfers were always corrupted, the skins sucked, and one day it refused to boot, citing an "unknown translation" as the cause (which makes no f*cking sense).
This has it's problems, sure, but it's a lot more reliable than Trillian and is CERTAINLY more eye-pleasing than the standard AOL AIM client.
