What surprised me the most is that Lenovo ships something as annoying as a loud fan (easily replaceable even for a home tinkerer). Of course they save a few pennies per laptop; but no laptop can ever be good if it's noisy. That was one of the main reasons why I bought an X301 ThinkPad many years ago, even when it fanned like crazy it was very quiet. But the clever design of the original ThinkPad's was starting to fade already then; the X301 actually had it's speakers on top. So you could spill liquid on it, unless you happened to spill it on top of one of your top mounted speakers of course.
I've also gone through a few ThinkPad's over the years, and ever since they stopped being IBM; they seem to loose more and more of the "premium feel" for every generation. Especially the keyboard is way better on my old T40 then on the one I use right now (T14).
