Robert McLaws has put it so well . I wouldn't want to say anything myself. But I'll add this there are many zealots who are not fortunate enough to be in one such programs but very much qualified to handle the responsibilities that come with participating in a software test program. Had I not been in the program that let me install the QFE and test it out, I would have definitely wanted to have it. But that's not because I am a fanboy (which I am) but because I know I have the skills...
