Are there to many options, MS, MAC, 100 Linux OS options,(Google Android)then another 100 other proprietary custom OS from other companies. Does anyone think we are increasing the gap between the middle age and the retired, older population. If medicine is intent on extending life and we are creating so many options that very often people are not using the same or similar OS. Just thinking out loud, it just seems like we are going over the top with the OS technology. Are we essentially dismissing everyone over the age of 40 as hopeless and no longer working to create user friendly applications.
