The ThinkPad X240 will work. Alternatively, the ThinkPad X1 Carbon (perhaps in its 2014 edition) with an adapter for VGA.

I have one with all configurable components. The clickpad is not working properly out-of-box and needs to be configured in the xorg.conf. The Ericsson WWAN also has issues, requires a line in udev rules. I did not try fingerprint reader, NFC and the card reader, yet. There are also issues with the Ultra Dock. After a firmware update VGA/DVI is working, but no HDMI/DisplayPort. The sound jack of the dock is not working either.

But so far I'm satisfied. The x240 is a decent laptop. It was a good choice to wait for the FHD model and not to fall for a MacBook Pro.

I got my x240 a couple of days ago and am trying to get the wwan card to work. What rule is needed for udev? And did you get the gps function to work as well?

I had to add the following line to /lib/udev/rules.d/77-mm-ericsson-mbm.rules for the Ericsson N5321 WWAN adapter:

ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="193e", ENV{ID_MM_ERICSSON_MBM}="1"

To be sure what vendor and product ID to use, you should check that first via 'lsusb|grep Ericsson'.

I did not care about GPS yet.

How do you find the keyboard compared to that of the X220 and earlier X series laptops? It's the one thing that makes me reluctant to consider the newer devices of the series.
