I tend to use my Macbook much more at home – even at times for reading documents and such. So I always found it difficult to keep another computer on just to use gtalk. Also didn’t have time to research on the topic till yesterday.
Which is when I realized that iChat was a Jabber client. And gtalk was built on the Jabber protocol. Which implied that iChat could be configured to be used as gtalk client. Cool. Because then configuration was a snap.
And now I can talk on gtalk on my macbook. Instructions on configuring iChat can be found here.
