Beautiful machine. Whilst my primary is now a 6 core/32gb desktop, my laptop is the OG X1 Carbon from 2011. I was waiting for the initial release and might have been the first to order it in Australia. It is still looking great today (chassis looks as if it could be just a few weeks old, true I've looked after it but it's also just that solid/high quality panels), although the new is of course hugely improved.
Their i7 only had 4GB of memory, so I got the i5 version with 8. Unfortunately - or actually, fortunately - there was a bulge in the chassis that tech couldn't get out so ended up returning the unit, and by that time the i7/8/256 was just around the corner so arranged for that to be the replacement.
Unit still works today, and I'm very glad I got the i7 CPU now. Much snappier than the i5, even though battery life took a big hit. On top of that, battery is worn out. I am probably going to look for another replacement battery soon, and am keen on a 2018 upgrade, but anyway for short development stints including Docker it is great. Keyboard is top of the class, so is the track pointer (which I love).
The upcoming 2018 version (8th Gen Intels) is expected to have 4/8c which will be fantastic. Sadly only 16gb memory, but Docker has kind of shifted my requirements there vs Virtualbox. (Perhaps I'll wait for a version where Intel has sorted their Meltdown issue.)
Co-workers are less likely to touch it and leave marks, that's the only upside I see.

I got a X1 Carbon a few days ago. I'm pretty content so far.
