I am one of those people who always gets a little excited when the next generation Apple product comes out ... and I confess to feeling a little bit of envy whenever I see people carrying the sleek-and-slim new iPhone 5. But I haven't had my 4S for very long, and don't think that an immediate switch is in the cards for me.
However, I also didn't think through all of the implications for the (sometimes subtle) changes in this hardware. My colleagues at WCG - Matt Snodgrass, Stephan Merkens and Patrick Donnelly - did an amazing job talking through the implications. Give this one a listen.
