Both people and hardware. In the case of people we olders have a different mind set we may be a bit slower but we just keep going. Kind of like the turtle and the hare.

I'm just going to assume your very inexperienced and possibly still a kid living at home. Because your comments have very little actual real life experience as far as old hardware not lasting that long and what is considered old and or what people can afford and not afford. If that were the case I wouldn't spot as many P4's machines still running in peoples homes and businesses.. My guess is that you still have mom & dad paying for things or you were born with a silver spoon in your mouth. Because the country I'm currently in, (which is the same as yours) is getting poorer everyday and broke is becoming the norm.
Old hardware won't last that long LOL thats a joke, I've loaded Lubuntu on 15 year old machines and many many 5 - 10 year old machines... I've also watched OS's drop support for hardware (particularly video cards) in just 2 - 3 years... So... like I said, little life experience.
Also this was a thread about "LUBUNTU" not regular Ubuntu so not sure how unity and all the other desktops got involved in this conversation.
Don't mind me, I'm only passing through.
