One of he podcasts that I listen to is Mobile Tech Roundup since I am such a gadget geek.  The guys (David Ciccone, James Kendrick, and Kevin Tofel) over there are given away anything from the Battery Geek website if you link to their site....so go visit Battery Geek and start listening to Mobile Tech Roundup.  I could use a cool battery for my tablet pc.  Now show me the geek stuff.
