As a two-way radio technician I have to disagree with you on your comment about Motorola lifespan. They will stop supporting the higher end radios around 10 years to force the police and first respondes to replace or upgrade the software. If they are taken care of and not beat to hell then they will be able to repaired for much longer than you would think. The batteries are not usually the cause of having to get a new radio. There are always after market batteries out there, and I have seen some last longer than Motorola brand.
Just my 2 cents worth of knowledge. 😁

Physical lifespan is determined primarily by two things..the robustness of the produce and the availability of parts if breakdowns should occur. I do not know what Canon's policy is on repair parts, but for most Japanese manufacturers, it tends to be pretty close to 5 years after the end of production. I have a couple of Nikon D300s that still work fine and fill a need for me. But key repair parts are no longer generally available for them. This includes the rubber grip pieces that must be replaced if the camera must be disassembled. So their lifespan, for all practical purposes, is "until they break."
A secondary factor is the availability of newer models which have features that you NEED and which your current model lacks. That one is a little more complicated.
In the case of portable two-way radios, by the way, life span is determined by battery availability. Motorola built a very successful line of two way radios in the early years of this century. When they decided that the life of the radios was over, they simply stopped making replacement batteries available. Because this is a niche market, those batteries are not available from other manufacturers. So the radios gradually become unusable as their batteries fail.
