There was a picture in the local paper last night showing a new Yamaha Clavinova recently purchased by the music department at the local Jr. College.  I do know they use and like them.

My wife was a music teacher for 35 years, is a bit of a Pureist about her music.  She prefers the real piano for sound quality and keyboard feel.  She understands the advantages, a Clavinova is much more portable and provides good sound quality in many instances.  She does not think a clavinova replaces a piano, but also understands the current crop of musicians prefer them because of their many advantages.

Reminds me of the controversy between acoustic guitar and electric guitar, some prefer to be unplugged and some like the electronic sound.

Better to play a Clavinova than no instrument at all.  We both hate recorded music backing up a singer, no fan of karaoke.
