Lenovo Thinkpad X1 Carbon


A bit of a shame: no docking port, neither FHD nor IPS panels available, only internal battery, fucking ram *fucking* soldered onto the mainboard, only two USB ports (one of it is only 2.0!), no real touchpad buttons...
And yet, its awesome. In a way more so than my X250. Well, not really. The latter is much more useful. But this one, well, it has style. So flat. Sleek even. Yet it is absolutely sturdy, no flexing at all (even better than the X250!).
Ah well: The panel is good for a TN panel, at least the trackpoint has real buttons, USB3 docks should work fine, the battery is changeable (internal, but neither glued nor soldered) and the ram is 8gb anyway.

Quirks


The Device performs pretty well. But it has some drawbacks. Most are minor issues:
  • The rubbery coating is rather delicate and gets scuff mark from just about everything
  • The battery is internal, memory is soldered
  • The fingerprint reader appears to be unreliable, although i did not test it with different software


Input Devices

  • The Touchpad is a bit iffy: it lacks real buttons, the thing as a whole can be clicked on the lower part, leading usually to cursor movement while clicking. Insufferable.
    • Setting AreaBottomEdge to around 9000 (either via synclient or xorg.conf.d) disables the lower few mm of the touchpad. Now the "buttons" can be used quite ok.


Verdict


Weeeell, a tough one. I really like it, despite its technical shortcomings. No socketed ram, no toll less changeable battery, no IPS panel. But its light and flat and really nice looking. So meh. The panel is good enough, the ram is plenty enough, the battery can be changed although it needs tools. The keyboard is ok too.
And Linux runs well, nothing to say so far. Except the wonky fingerprint recognition.
