We Don't Need No Stinkin' iPod
I've been using a Northgate pocket MP3 player that I got off eBay for $10 to listen to podcasts during my lunchtime walks or while driving. It only has 64 MB of memory, but that's enough to hold several hours of voice, and it mounts like any other removeable storage device when plugged into a USB port. For the price, it can't be beat.
I came across a blog entry entry written by someone in almost exactly the same situation, but he's taken it one step further. By storing not just the podcasts on the unit, but also the podcatching software, he's created a self-contained device that will automatically check feeds and download podcasts by just plugging it in to a USB port. Very cool integration of several key components to make an all-in-one solution. I even use the same software as him (Doppler).
