GMail trick

That you may or may not know about. It's as simple as : foo.bar@gmail.com is equivalent to f.oobar@gmail.com is equivalent to foo.bar+some_random_string@gmail.com

Pretty handy when registering on websites (create one address per site and see who's guilty of spammer-fluffing for example).

Adobe Reader 9 on Windows 7

For all the people that might be having issues with the setup of Adobe Reader 9 on the beta version of Windows 7, try and set the compatibility mode to "Windows Vista" (download the Vista installer on Adobe's website).

That did the deed for me, hope it can be of help.
