First of all, the title of this article is misleading. It should have "Opinion:" in its title, as most parts of this article are based on the author's opinion. I think the title should also be "Considering an alternative to modern ThinkPads? Try Elitebook" instead of what it has right now, as the article itself does not compare modern Elitebook with classic ThinkPad at all. The entire article compares a modern ThinkPad with a modern Elitebook. I was quite excited when I read the title because Notebookcheck had some great articles regarding old ThinkPads, but I have to say I am disappointed with this one.
Then it comes to the discussion of charging ports. This is the first and only article I have seen that prefers a dedicated DC charging port than USB PD, with the only reason that USB-C charging port is more likely to fail. While the USB-C issue with recent ThinkPad is real, there is no evidence that USB-C charging ports in general are more likely to fail than DC charging port. The USB-C issue with recent ThinkPad is from a mal-functioning firmware, and the same firmware issue can happen to a DC charging port as well since some modern laptops use programmable circuits to manage charging. DC charging ports aren't magically more reliable than USB-C ports. My MacBook Pro had a faulty MagSafe 2 charging port after a year of normal usage. I don't want to sound like "I don't have this issue so it doesn't exist", but none of my USB-C equipped ThinkPad (X1 Carbon 5th, X1 Yoga 3rd, T25 Anniversary, P1, T495) had any issue with USB-C or Thunderbolt.
Other sections in this article do not show how Elitebook is "better" than a modern ThinkPad, with the only exception that Elitebook still has 2 RAM slots and upgradable M.2 slot for WiFi. Mostly, the article only shows that an Elitebook is a valid alternative option. Still, as I said in the first paragraph, nowhere in the article did the author compare a modern Elitebook with an "old" ThinkPad, which the title suggests. It doesn't show whether the Elitebook has drain holes like the classic thick ThinkPad, whether it supports battery hot-swap like classic ThinkPad, or whether it has comparable keyboard with a classic ThinkPad (not a modern one as we all know that classic ThinkPad has much longer key travel and taller TrackPoint).
