if i remember correctly, skype for windows works in wine...or was that teamspeak 3...
i don't like the skype client for windows that much, it can be a bit confusing if you got 30 convo's going on at once
i've been known to start talking about something to the wrong people
(thankfully i reserve my trash talking in email or i'd be red in the face at times or worried more
as for the linux client, i do wish they would update it at least, maybe not make it just like the windows client, but more "organized" if that make sense, right now it reminds a lot of the old msn client as it is, and the sound quality at times isn't all that great, and some of my friends have complained of an unexplained "squeal" on my end, only happens in skype, but not in TS 3 or vent...happens with pusle/oss/alsa, so i'm not sure what exactly causes it, as it i don't hear it on my end.
