I think we have gone way past the ideal weight for laptops. My favorite laptop weight wise was an HO from 2009. It was 6 pounds. That thing was great. You could sit it in your lap, and it would stay there. I have a MacBook at half that weight, and it slips off my lap constantly. Part of that is the material, but part of it is that it is so light.

I really wish we could start focusing on ideal dimensions, rather than focusing on extremes just for the headlines.
