I'll wait on UK pricing, availability, and I presume it is the case that they're being lazy and not creating a UK keyboard with an inverted and mirrored L shaped return key.
I did have a Thinkpad 701CS, it was quite good, but the expanding keyboard was just not as durable as normal thinkpad ones, the hinge eventually started failing, and the screen resolution was rather low.
Currently still on an X61, but web browsing is a bit slow in OpenBSD (part of this will be BSD's fault). I was pondering an X230 with a 220 keyboard and a new screen transplanted into it (this is possible), but now the 25 is out it's a little tempting. A little disappointed by screen resolution and lack of a thinklight, but the discrete GPU and thunderbolt are decent additions.
I've used lots of Thinkpads in the past, the X40/X41 had a lovely form factor, but the dog slow custom hard drive was awkward.
