I'm looking to buy a new laptop and was wondering if anyone had some recommendations. The one I have currently is a gaming laptop but the battery is complete crap now and the laptop itself is pretty heavy. Want to sell it and buy a new lightweight travel laptop. Will mainly be used for everyday tasks and no gaming. Might use engineering programs if it can run them. Also, debating between an ultrabook / chromebook? Budget is about $800 or less. Any suggestions?
