Almost all modern laptops are 'good' my wife's lenovo G500, was cheap, decent quality, sufficiently powerful for non gaming needs, and had ethernet, it just wasn't light or thin. And that's the problem, ethernet ports are, bluntly, fat. And that doesn't sit well with thin.
8G of Ram, 500GB of storage, or less if you have storage on your desktop, down to 200GB minimium, and an i3/pentium and you'll be fine, the form factor for use lying down is the biggest issue, if you are the size of my mother-in-law a 15.6 inch non thin laptop wouldn't work as she is tiny. For me i'd be comfortable up to 3-4 Kg of laptop, that choice is down to you.
