I'm looking for one around $300 to $400. I want a 6 or more hour battery life and a 15 inch screen. Preferably 8GB of RAM. The more battery life the better. I'd like an SSD but it's not a requirement because I have an extra 2.5 inch SSD anyway. Condition can be used, new, open box, or refurbished just as long as it's in good condition. I don't need it to be able to game. I can just stream games from my desktop anyway. The OS should be Windows 10. I'd prefer 1080p resolution but 1366x768 is ok. Also I live in the US.
