In April 2007 I bought a Sony, VGN-N250E, from Best Buy in Lafayette, Louisiana where I was living at the time. Vista Home Premium as the OS. I also bought a wireless router, and a Vista compatable printer. I took all one day setting up the system and getting wireless. Every three days Vista lost all of the drivers to all of the attachments and refused to connect to the internet, Vista telling me to "turn the wireless radio on"!! Needless to say the radio was on. I would spend hours setting it all up again, only to lose it again every three days. Best Buy said it was the IP. (RIGHT) I finally, after six weeks of this, had XP Pro installed. I lost all of the content Sony had installed (the Media Package), the mic/earphone jack no longer works, none of the built in card readers work, but I have been using the computer now for 18+ months with NO trouble connecting to the internet, using my printer, etc. Sony tells me that in order to FIX the things NOT working on the computer will require another install of Vista, as the computer is built to work with Vista only. Vista sucks and has ruined MicroSoft's reputation, period. Bill Gates and associates should be ashamed of themselves for marketing trash!
