I have watched the 2006 series starring David Tennant as the Tenth Doctor when the Cybermen returned in Rise of the Cybermen and Age of Steel. After that I followed every Cybermen episode there was. After watching a season of Matt Smith (the 11th Doctor) I started watching the classic series of Doctor Who. And I loved it. I would recommend for iTunes to make the following episodes available for watching: The Tenth Planet, The Moonbase, The Invasion, Revenge of the Cybermen, and Attack of the Cybermen. Having those episodes on my iPad would make my day.
