I completely concur with the observation that it teaches responsibility and how to take care of things. It goes hand in hand with pride of ownership, and learning not to treat everything as if it were a disposable (a growing trend among our youth, and this world.)
I still have my Boston Acoustics A60s from my first system that my father bought me when I was 12. I refoamed them last year (boy, did that ever help!), and they sound excellent for their age - sealed cabinet, high efficiency, 8" bass/mid driver - mates well with the little ASL wave 8 tube monos I have in my bedroom system.
They still look quite good and sound great after 16 years. They even survived college - perhaps the strongest argument that these concepts were passed on successfully.
Perhaps in 16 years, your daughter's B&W monitors will still be in use somewhere in one of her systems!
