Somehow I don't believe a mouse click has any legal weight (like a written signature would).
By the way, I occasionally read the "Aggreement" purely because i'm bored. And you really should read Windowz's aggreement. The latest version states that a if you get a new motherboard you need to get a new licence as it constitutes a new PC!!! I mean like, seriously how can that be fair?
Personally I also read instructions occaisionally - the Windows 98 instruction book is hilarious! The way it describes the "mouse" pmsl!
