I have been using testing on two desktop machines and an iBook for for
up to two years now. I have never had anything break in testing and its
pretty close to the cutting edge.
I don't find testing as cutting edge as desirable, at least for some important packages for me. Moreover, I heard that sometimes testing is more unstable than unstable, and that when testing breaks, your face gets a different color than that it gets when unstable breaks. ;)
Don't know if this is a well based information, though.
