Podcasts. I'd been interested in them before, but because my old mp3 player was a bit dodgy, I'd really only listened in on my desktop. As a result I'd stuck mostly to screencasts, and largely bypassed podcasts altogether.

Knowing I had alot of traveling coming up, I recently upgraded to a new portable music device. I loaded it up before I left, downloaded some technology content, some news podcasts(Meet the Press, and Wall St Journal Tech Week), as well as some comedy (Ricky Gervais - the guy who created The Office - is hiliarious) 

Loaded up, I listened to podcasts as I went from Seattle->Denmark->London and back again.  Annoying lines at customs that were 4 rows deep didn't seem so bad. The 2 block line to get through security in Denmark, no worries - I was being entertained and educated with an interview of a tech legend. Podcasts are a beautiful thing.

I was looking forward to this before, but even more so now - I'm sitting don with Ron Jacobs next week to record a few ARCast sessions. Ron is part of our Architecture Strategy Team and does some great podcast work that's posted up on Channel 9. 

If you've not come across the ARCasts yet, I'd definately recommend checking them out.  You can find them here: http://channel9.msdn.com/shows/ARCast_with_Ron_Jacobs
