Of course you know that I have an iPhone and while there are a few things I can complain about (no syncing of Notes or iCal to-dos, no mail rules, "scrubbing" works poorly on long format content) I am very happy with how well it works as a phone, iPod, and portable Internet device.
If you have an iPhone or are considering one, you may want to listen to the Apple Phone Show podcast (iTunes link). It’s hosted by Scott Bourne and has Andy Ihnatko on most episodes.
It’s a decent short-format podcast that runs 30 minutes and is only once a week. Each show, they discuss recent events, occasionally cover rumors, review iPhone accessories, and share tips.
