Listen to InformationWeek On The Unofficial Apple Weblog Podcast

I was honored when Michael Rose, an editor at one of my favorite Apple blogs, The Unofficial Apple Weblog, asked me to appear as a special guest on TUAW's weekly live Internet radio show. Listen here.We talked about iTunes variable music pricing, the iPhone App Store nearing one billion apps sold, the latest round of Microsoft anti-Apple commercials, and more.

One thing I'd hoped to bring up, but didn't get to, because we ran out of time: Mac sales. They were down year-over-year in February and January; Apple is getting hit much worse than the Windows PC vendors. Two months of data isn't enough to call this a trend -- however, it may well be that we're seeing a historic transition at Apple, with the company becoming a media and phone vendor with a PC sideline, rather than vice-versa. I'll be keeping a keen eye on the March sales estimates from analysts, and official quarterly sales results, when they come in.
