You can win Windows 7 Phone by writing only 140 Characters. You need to leave a comment over here: SQLAuthority News – Win Windows Phone from Idera in 140 Characters – A Cartoon Challenge of SQL over here. There are so far around 150 comments and I believe that chances of one person to win the contest is pretty decent.
I have been personally using Windows 7 Phone for quite a some time and I really love it.
