The primary purpose of the EOMA68 specification is to bring end-users the right to upgrade their own mass-produced Computing Appliances. To make end-users lives easier, purchasing decision-making should be made not on technical interface capabilities, neither should they be expected to have significant technological expertise.
EOMA68 products are completely unlike throw-away single-purpose SBCs (Single-Board Computers) and throw-away hermetically-sealed monolithic devices: re-use, re-purposing and upgrading is encouraged, resulting in a greatly-extended lifetime for both Cards and Housings than would normally be expected. It is perfectly reasonable to expect any Card to change hands five or more times during its useful operational lifetime. (Source)
