Thinkpad X1 (Yoga/Carbon) do great for heavy use developer laptops. I use them since the first generation, with Linux as operating system. Never had serious issues with drivers, even wacom, digitizer and auto display rotation are working nowadays, not to speak of USB-3, fingerprint sensors, etc. The whole device is a no-brainer and just works.
A place I work used to order them for developers, they're awesome little machines but not without their issues too. We had constant issue with them no longer charging for people, something on the motherboard related to charging would just die sometimes machines only a few weeks old would do this. You'd start your day, try to start up your laptop and it would be dead and require sending back to Lenovo (which to their credit they would fix and return within a reasonable time frame.)
In the company I currently work, we have the option of MacBook Pro's or ThinkPad X1 Carbon. I never seen such a problem. I am not saying that it does not exist.
Yeah, after many, many problems with Dell's and HP's (I worked at IBM and we absorved thouthands of such machines on outsourcing deals), I recommend ThinkPads, Series X, T, P.
I have looked at Thinkpad x1 carbon, and they are so expensive! People complain about Apple Tax, but the x1 Carbon is so much more expensive for what it does.
Are you comparing based on the base price, or the "discounted" price? (I ask because Thinkpads seem to almost always have a 20 - 50% off sale - right now I believe it's 50% off).
