It's not that hard to get a high resolution laptop. For example, the higher end ThinkPads always always offer a WUXGA (Wide Ultra eXtended Graphics Array
Resolution) option for up to 1920×1200 resolution.
When you say higher-end, do you mean larger or something else? I would really like to see replacement options for my Sony laptop, which is a 13.3" with a 1600x900 resolution, but from what I can find, only Sony has a nice resolution (1080p now) in that size. Does Lenovo have something that I've been missing?
