35mm film and how much we are required to waste
A digital camera has a functional life of probably 20 years before a fatal, catastrophic electronic failure renders it unusable. This is required in order for the product line to endure the median stress levels the average consumer is expected to present, and keep remedial maintenance costs under control.
Yet, these camera will typically be obsolete, abandoned, or shelved permanently within an average of two years.
By my extensive calculations, it appears that digital technology has about 90% built in waste!
