One of my favourite mobile reads is Murray's blog over at Palm-Mac. Never one afraid to give his opinion of all things mobile, I always find his posts largely to the point, observational and usually with a little humour attached too.
Now though he's expanding into the world of podcasts. His view is that the Palm podcast world is very stale (I don't tend to listen to many podcasts myself, but I'd agree with him from what I have heard), and of course he feels that he could freshen things up a bit with his own contribution.
This sounds like an interesting project, so I'm awaiting his first podcast with bated breath. Good luck Murray!
