Fire
Man, all this stuff about msn charging for the use of messenger really stinks. I certainly would never pay for that, even if there weren't free alternatives.
In the mean time, I just got Fire after reading about it in this thread. Took a bit of getting used to, but now i love it. Its like the trillian for mac, in that you can connect to a bunch of services, aol, yahoo, icq...
i only use it for msn, but i still like it a lot better than messenger, its a lot more customizable. The most important thing for me is being able to change those freakin annoying sounds that messenger doesn't let you change anymore. This thing lets you choose any sounds on your system, i like keeping em soft and subtle, no f---ing xylophones and bass drums. as i spend a good chunk of my time doing homework while online, this is very important in determining how distracted i become. (i know i can just turn the sound off, but i like knowing when people are talking to me...). You can even make it so that certain contacts have their own specific notification things and so forth.
Its also cool to have the whole brushed metal osx look going, now i cant tell any of my damn windows appart, i love it, hahaha.
My only complaint is that the screen names don't seem to update, which is a problem since my friends often insult me through their names, and i gotta keep on top of these things.
