Good job with the review, but you didn't say anything about the terrible keyboard layout! More specifically, two choices stand out as immensely stupid:

1. The arrow keys are in NO way delimited from the neighbor keys, so without any means of reference the fingers won't be able to find them quickly and will almost always hit the wrong key, which is most annoying and practically this alone makes using this keyboard a real pain when typing fast is a must

2. The 'End' key was removed (?!) and replaced by the Power button (what??!). The only 'End' key is the one on the numeric pad (key '1'), but alas, that's subject to 'NumLck' not being active. Not to mention that again it's absolutely counterintuitive to have to go from the top row where 'Home' is to somewhere in the middle of nowhere 4 rows below for finding the counterpart 'End' key - again, with no way of distinguishing it from the neighboring keys

What was wrong with keeping the Power button separate from the keyboard? What kind of optimization was that? Definitely not the brightest design choices from Asus!!

Maybe worth putting in your best displays list ?

For some reason unknown, Asus don't put a num lock interactor led in their N notebook for years, and their cap lock light is not in a place where you will easily spot when u are typing. I don't know if  it is only me, but it is inconvenient.
And why there is only three usb 3.0 when they they used to have four with my N56vz. The new n551 didn't got much thinner or smaller. it suggested the cost cutting prevent they make the notebook as good as they can, and it is annoying. Even though it is still a good notebook, you know in the back of your mind that it could be better.

Numeric numpad is really disappointing.
