It sounds like a good idea: touch up a messenger for the new OS and it should clean up some problems. but why? There really is not much of a reason to use proprietary instant messenger systems anymore. I do not have contacts that only use one of the big named messengers, and neither do most people who IM. There are perfectly good multi-tools out for every flavor of OS. Adium, Pidgin , Digsby and others are great examples. Quit using one trick ponies and hook up a big rig (which usually consume less resources on you computer than the big brands).
