Aloha Everyone!  Windows 7 has been out for over a year now and if you are deciding to do an upgrade from Windows XP or Vista there is a free tool from Microsoft I would recommend you run before doing an upgrade.  The tool is called Windows 7 Upgrade Advisor.  

Aloha Everyone!  If you are tired of Adobe Reader and would like to try a new PDF reader than give Nitro PDF Reader a try.  Nitro PDF does a bunch of tasks that tend not to be free in a PDF reader.
