That's not true. My grandmother has a old piano in her house. I think her father bought it used in the 1920s or 30s. It's an "Ortiz&Cussó", a brand created in 1898 and, based on some findings in the web, that piano could have perfectly one hundred years. And it even survived the 700km travel when my grandmother moved to another city. It has lost a lot of volume, some keys are "bited" and some strings get easily out of tune. But, believe me, it still sounds great. The lower range of notes beats most pianos I have heard (and played). It needs maintenance, but it's not useless. I think a piano can last a lot of time if you take care of it.
