The lifetime of "appliance" type electronics has always been much longer than that. In my first job, in 2012, I was using electronic test equipment running Windows 95. Anything industrial has a lifetime of 10+ years. Most electronics doesn't need to be cutting edge - and non-cutting-edge electronics hasn't really changed much in the last 15-20 years anyway. If we want this type of technology to actually be useful, it should have a lifetime somewhere near the thing it replaces. Otherwise schools and universities will get burned once and go back to whiteboards. 8 years isn't really acceptable.
