We should cover: 1. Original cost including tax (which could be almost 10% in some states) 2. Cases (if used - where some all-glass phones literally *require* a case) 3. Batteries (if required, including those required to maintain CPU speeds) 4. Useful items (e.g., courageous non-3.5mm earbuds, SD/SIM cards, etc.) 5. Minus current Ebay/Amazon used resale value (realistic numbers please)
It would interesting to see your total cost of ownership over 5 years.
