I recently bought a Dell desktop w/ Vista Home Premium and 4 gigs of ram. I noticed that vista only recognized alittle over 3 gigs. I called Dell tech support, and they said that they know that vista (32bit)can't support 4 gigs. They switched me over to customer service, and they said that they'll give me a $50 gift certificate. I told them they're charging $100 for a gig on their site, and they gave me a $100 gift certificate without needing to return the 1 gig ram. Sometimes it helps to complain alittle.
