IM with voice

Being a user of the world's only OS exlcusive to it's hardware, you would think that you're special. But being in such a niche market, being only the 5% percent of the computer users in the world, you're really in a disadvantaged position. Yeah, some applications maybe tailor-made for Mac users, and some may have spanking ways to launch or close or use a software, but there are also disappointments. I have been looking for IM clients with voice to use with the built-in mic in the iBook G4 but it's a futile attempt. Yahoo! has set aside the development of their famous Yahoo! Messenger for Macs. Thus OS X users are left with a barebones Yahoo! Messenger. The recently released beta version of GTalk from Google doesn't have any native support for Macs, one has to use a different IM client such as GAIM and sync to the google talk servers just to use the functionalities, which I could say is very nil. Yeah, there's PROTEUS which combines all these IM clients into one but it still lacks what's in Windows. Now I'm beginning to think that the glass is half empty when it comes to mac applications.
