Ok enough jokes about ms windows...
they wern't funnt anyway.
I think that this is a mistake on the part of google, regular users *WILL* download this without reading the disclaimer and recieve a terrible experience, they will then attribute this experience to google therefore google = shoddy software and they wont use it again...
I have seen this happen so many times its unreal, My favorite was a post on a forum about exeem (beta) it went something like "I wont be using thissoftware again and will be advising everyone I know to steer clear, I have the latest beta version and it still acts unexpectedly, its just not professional." or something to that effect (To be fair the main point of exeem was to provide another p2p sharing program, so you should really steer clear anyway...)
