If you want some insight into why the iPod is such a smash success - and why Microsoft's Zune will have a tough time getting a solid market foothold - check out National Post Robert Fulford's recent column. At 74, Fulford likely falls outside the iPod's "target market" but the fact he finds his Nano  "the finest private luxury object of this century so far" reflects how the iPod has resonated with so many consumers (more than 60 million and counting to be precise). If Fulford starts publicly pining for an iTV device, you know Apple has scored another home run.
