I have hundreds of cassettes (mostly Middle Eastern, Indian and Western classical, with a few jazz and folk), have several cassette players, and listen to them regularly. The sound quality is dependably better than MP3 (at least any MP3s I can get and any equipment I have access to for playing them) and the 20-30 minutes of one C60 side is a convenient length for a lot of music (like most classical concertos, symphonies and chamber works, or a typical recorded raga). I don't see myself ever wanting to convert them unless to send one via the Internet.
