Some Queries

I am going to buy one MacBook.I have some doubts. Pls clarify these:
1. I am having one wireless dsl router. Can I connect it to Macbook.
2. C,C++,Java compiler is available for Mac?
3. I have heard that gtalk is not supported in Mac. So if I want to video chat with someone who is not having Mac then what is the way to do it.
4. Does MAC has codec support for .avi,.3gp,.flv, .wmv etc?

1. yes
2. yes
3. iChat, Adium or right from the google talk web page



4. yes, what phone do you want support for?, yes, yes unless it has DRM

I prefer to use iChat for Google Talk and AIM. Adium does not support audio or video chats yet.

In response to (4), you should download Perian - The swiss-army knife of QuickTime® components. As for .wmv files, download the free WMV Player.

Also, for video chatting with a PC, I think Skype is the best. It's free for computer-to-computer text, audio, and video chats.
