Talkcast is back Sunday 10pm ET with special guest Tod Maffin

If you haven't tuned in yet for last week's talkcast, go check it out — it's been up for a few days now, but the higher-quality version got lost on the way to TalkShoe's servers and I just got it re-uploaded. You can hear Mike Schramm and me talk football, MacBook Airs, and (with listener Tony Walla) discuss the prospects for WiMax on future Mac laptops. Download direct, or subscribe to the TalkShoe feed in iTunes. We are hoping to get the main iTunes feed back up and running shortly, just in time for some tasty screencasts now in the early stages of production.

Join us again on Sunday night for our next live show, 10 pm ET as usual. We'll be joined by a very special guest: Tod Maffin, technology columnist for the CBC. Tod is a Mac user, so we'll be quizzing him both on his general view of Apple and specifically on the company's prospects north of the border (assuming there's ever a Canadian iPhone!). Should be a fun show, so mark your calendars.

Update: We're going to try something a little crazy — simulcasting in video at Yahoo! Live. Swing by http://live.yahoo.com/tuaw before the show and see the insanity in progress.

As always, you can join the conversation on TalkShoe either with or without an account by using the shiny new browser-only client, no downloading required and no registration needed. Just click the "TalkShoe Web" button on our profile page at 10 pm Sunday. You can also listen in on the Talkshoe page or call in on regular or VOIP lines.
