Macworld 2010 is all-systems-go in San Francisco, and although Apple isn't in the mix of presenters this year, there's plenty going on at the show.

Macworld Editorial Director Jason Snell joins PCWorld editors Robert Strohmeyer, Jason Cross, and Tim Moynihan to talk about the emerging cottage industry surrounding the iPad: carrying cases, iPad apps, modbooks, and...Halloween costumes?

In other news, Google Buzz is trying to make its mark on the social-networking world, and we've been using it for a day or two. Does it have potential? Is it just another Google Wave? Can it coexist with other social networks instead of destroying them? Is it getting in the way of your Gmail inbox? Listen in to hear whether the editors think Google Buzz is buzzworthy or just a buzz-kill.
