I've tried it and, after a few hours of giggly feeling of fun, the sense of falling begins to annoy you and you being slouching to maintain the balance. It also becomes hard to type normally, unless your ball (no, not that ball you perv) is really large to provide elevation. It just didn't work for me.
I think a better alternative is to sit in your normal office chair but take a 5-minute break every hour and a half to stretch and do some light exercise.
