In Africa? Almost all broadcasts in West Africa are digital, requiring a specific STB from the broadcaster. The TV does not even need a tuner, let alone one for the supposed local standards.Can you repiar olnew TVs?
I live in the UK, and I am using a desktop 3 years old, the family PC is over five years old, and our laptops that are 5 year old Lenovo T61's because they are better than the newer models. We dont play games on PCs - we have Android phones for that. PCs are for LibreOffice and Firefox (and the occasional bit of PCB layout). I think our company (Sun) servers are also more than 4 years old. They work fine. If it aint broke, don't fix it.
More relevantly: West African transport operators want mechanically injected diesel lorries with no ECU's because if the ECU goes wrong, the lorry and its load are lost. This means buying old lorries. The Western "polution reduction" Euro 5 etc, is about lining pockets for "Add-blu" sales, not about saving the planet.
