I have a dell studio laptop 1555 with their optional screen upgrade, so its 15.6" but fullHD 1920x1080.. at the office/home I use it on a separate flatscreen.. 15.6 is too small for comfortable work at resolution that high, but if you need to FIT everything, it will do.. Plus you can always lower the resolutino, or use zoom in browser. I really like it as a solution, battery life is good, not too heavy to lug around, has full HD, and combined with external monitor + wireless kb/mouse its great. Theres also HDMI output if you want to use it on a fullhd lcd tv
I think they're still on sale at dell.com and they're below 1k, worth every penny.
