Now that H.264 is available for PC and they have enough experience programming for x86 Apple should really step up and bring iChat to Windows. They should add some SIP compliant VoIP function and really try to steal some of MSN's and Skype's user base. The only reason why they might not be doing this is because they are currently relying on AIM more or less and may have a contract that forbids them to enter the Windows market. I guess although Apple has just introduced new functions to iChat, I don't think they suffice. The problem I currently see is, that with all the new apps emerging that support VoIP, which all bring a new text protocoll, the IM world is getting spread out more and more. I am all pro choice and competition but interoperability would not only be nice but I think a necessesity. Multi-protocoll clients cannot keep up with the current speed of new protocols and you end up using more than 1 or 2 clients, which is just annoying. I think Apple has the power to actually become a defacto standard like MSN and Skype is looking to be and end this crazyness. What do you guys think?
