I would like some opinions.... Since April 08,when I purchased a refurb. Gateway M6307, I have been using Vista without SP1. After reading all the problems reported after installing SP1 I decided not to install until the problem reports abated. Let me also say I have had no problems whatsoever after learning about and using Vista. I have no desire to screw that up. Here are a few questions.... How do I know I don't already have SP1? Was it around in Feb.08 when this box was refurbed and Vista installed. What prep. should I do before download & install? Where should I download from? Is it best to be hardwired? Is it worth it?? I have had No problems!! The Box is fast & error free!!
