My primary reason for selecting this HP laptop was to display interactive, 3D and color network/infrastructure diagrams to small groups. Unfortunately, the battery pack is strained to support this activity without plug-in power. Also, I was disappointed to learn that the laptop was not equipped with a backlit keyboard which I (mis)understood to be provided. I’ll be curious to see if future HP 17-inch laptop models address these shortcomings. Otherwise, a powerful and versatile laptop for mobile project work.
