Talkcast tonight, 10 pm ET: Macworld Expo preview

We're back live tonight with the usual gang of ruffians, this time (partially) live from San Francisco as we warm up for Macworld Expo 2010! So what if the iPad isn't out for a few more weeks? We're revved up for the show — it's our first year with a booth of our own, and our first year livestreaming video directly from the expo floor — so what we need now is to hear from you. What coverage do you want to see, which products do you want reviews, who are the pundits and industry veterans you want to hear from? C'mon & call the show to let us know.

We'll kick things off at 10pm Eastern (7pm Pacific); hopefully the Superbowl will be over by then, and if not, we'll vamp. Once you sign in on Talkshoe, you'll be able to call in with your own phone and chat live with TUAW bloggers and listeners. See you then!

To participate on TalkShoe, you can use the browser-only client, the embedded Facebook app, or the classic TalkShoe Pro Java client; however, for maximum fun, you should call in. For the web UI, just click the "TalkShoe Web" button on our profile page at 10 pm Sunday. To call in on regular phone or VoIP lines (take advantage of your free cellphone weekend minutes if you like): dial (724) 444-7444 and enter our talkcast ID, 45077 — during the call, you can request to talk by keying in *8.

If you've got a headset or microphone handy on your Mac, you can connect via the free Gizmo or X-Lite SIP clients; basic instructions are here. Talk with you then!
