perhaps there is something about Trillian that is familiar to the person using it? why is it always up to the Linux people to choose what they think everyone will like? seriously...
and why all this Wine hate? it opens Linux to far more programs. part of what makes Linux work. why all this 'you must only run GNU stuff and NEVER Windows stuff' attitude? You do realize that the biggest reason for most people's resistance to Linux is because there are some programs they refuse to give up? maybe you see no problem but you are not everyone else...
