With the release of OS X Tiger comes iChat AV 3. While the video conferencing may not live up to the hype, as you need Dual 1GHz G4’s, or a G5 to initiate a 4-person video chat, the addition of support for Jabber - “an open, secure, ad-free alternative to consumer IM services like AIM, ICQ, MSN, and Yahoo” brings some interesting chat options into the mix. Most notably, you can now use iChat AV 3 as an MSN and/or Yahoo messenger client. While all-in-one applications such as Adium exist, it’s nice to be able to use iChat’s nice interface to handle all of your IM needs.
