Bunged it on an Elitebook today
Folio 1401 or something, I think. Everything worked bar the trackpad on/off shortcut button, but the actual trackpad system settings works perfectly. Was up and running in 20 minutes, all updates installed, propietary bits installed, dual monitors over Displayport working perfectly - happy happy.
I could have gone with Debian (and I do for servers) but years of using Unity at home mean I'm used to it's layout and have a decent workflow sorted with it, so Umbongo it is for the works lappy. AS someone noted further up, I want something that works, and credit where credits due, if you aren't too fussed about being fully FOSS (the proprietary stuff sticks in some OSS peoples craw a bit - which is fair enough) then Ubuntu generally works better on more hardware than most other distros IME.
Anyway, seems like a solid release. Carry on.
