I've got a 3rd gen and I like except for button-less mouse, the weird touch-strip for the function key. They fixed both of these with the 4th gen though.

I use Arch and pretty much everything "just works," the camera, sound, wireless, etc.

I have third gen X1 Carbon and I love it, I run openSuSE leap on it and I have never been more satisfied with a linux distro on a laptop.

I wonder what the heat is like. All these slick looking things seem to get rather hot. Real X-series with throttling seems OK.

It's rather absurd. Even the Nexus 9, doing light tasks, gets uncomfortably warm.

If it was a bit cheaper and had a 13" screen (or a smaller rim) I'd go for it. Right now the XPS 13 has an edge for me.

I really want to get this one but have a few concerns -

I'm running a Lenovo S540 (the line has been discontinued but it is an ultrabook). It's processor isn't as good as the 4th gen X1 carbon you can check the comparison here: https://www.cpubenchmark.net/compare.php?cmp%5B%5D=2608&cmp%...

My S540 has an SSD,16gb ram and the slower processor and it churns through work fine, I mainly do Java development and on top of that I use the Play Framework which compiles to both Java and Scala so it's more CPU intensive.

I can easily run one or two IDE instances alongside 10+ chrome tabs,several terminals and mongo/mysql db GUIs.

I keep been tempted by these.
