Apple is firmly behind “Touch” interfaces on all of it’s devices including the iPod touch.
For years Apple has continued making the iPod Classic with click wheel but the writing is firmly on the wall as to the future of click wheel iPods. Apple recently removed the link to iPod Click Wheel games on the App Store fueling speculation that the iPod Classic click wheel models will be discontinued. For now the Apple store still shows iPod Classic click wheel iPods in stock but you will no longer be able to purchase extra games to put on Click Wheel Based iPods.
It’s hard to believe anybody purchased click wheel games for the classic ipod but at the time they were removed from the app store there was about 50 click wheel based games available for purchase.
