I desperately need to replace my highly problematic laptop. HP - never again. Unfortunately, I don't know much about the technical aspects of computers, and trying to do research is making my head spin. This site was recommended to me. I'm a grad student who does a lot of internet browsing and word processing while also using Pandora or Netflix. Good audio would be nice. I'd like to have the option to do gaming, but I don't expect I'd need something capable of handling the most strenuous games. I used to play WoW, and I might think about getting back into it if I had a computer that didn't ridiculously overheat. I don't necessarily need something mobile for long distances, just something I can move around the house, but more mobility would be a bonus. Strongly prefer screens close to 15 inches or higher. I'd like pricing to be closer to $1000 than $2000, but may be flexible for something awesome and not problematic. Help, please?
