Do you still use compact discs?

I was browsing a technical store's website and came across some DVDs. On sale. You'd need an optical drive to use them, unless you use them to decorate your walls

If you do use them, what do you use them for and why do you not just use hard drives, SSDs or USB thumb drives instead?

This is not a hate post. My whole existence is living in the 90's, so... :P
