Its the Screen/keyboard/mouse that matter, followed by battery life.
What dell have always done baddly:
1) All laptops SHOULD have three mouse buttosn so you can cut N paste properly in X11. Anyone using linux and not agreeing probably use a window manager that clones Mac/windows.
2) Keyboard action is poor on most laptops, and the reason why I have not asked for a new work laptop, as an old Lonovo is just better keyboard.
What all laptops have doen badly for a long time.
!) I want pixcels I dont want size. So I want the highest DPI you can put into a laptop on a maximum 14" screen.
2) I work with Text not with moovies so give me a 4:3 screen ratio, but at least HiDef native resolution horisontally.
What no one has ever done right.
I want screens that allow me to code in the park during summer rather than in the office.
