What type of computer do you have? And what is the one you like to have?

I have a Sony Vaio which is pretty good but could use an newer computer. Not sure what I really want but I know whatever it is I don't want Bill Gates windows operating system on it. I want Linux hate Gates snoopy systems that let virus and spyware through his backdoor spy holes. I think I like the Sony but might go for a Dell as heard they are pretty good. Not sure what would be best acutally as Not that computer software or hardware saavy about operating systems but hubby helps so I learn more and more. I would love to have a lap top as well as I only have an at home PC desktop.
