Happy T560 (same laptop, with a 15'6" screen) owner here. Fully agree with the post conclusion: "powerful, has a very long lasting battery, it is silent under normal work and you can get your stuff done quickly and get solid Linux support. The Linux support is so good that I’m wondering why they do not ship it commercially to attract people like me."
EDIT1: To dig further: compared to half a dozen linux "tweaks" with my former Dell XPS laptop, I have zero with this Thinkpad. Everything works as expected, no hardware-related config whatsoever. This is using Arch Linux, which ships a recent kernel.
EDIT2: I bought the larger T560 version because I like the simplicity of doing everything on the same machine, but I'm more often using it at home than on the go, so the mobility / screen size trade-off is easy for me, and it's still relatively light (it's relatively thin, unlike W series).
