Final notes: There's a 14" Samsung also available which has an optical drive, and a dedicated GPU but has worse battery life, weighs more, pricing still un-announced.
Build quality is slightly superior on the MBA, the Asus isn't far behind but the Samsung is lagging quite a bit.
The Asus has tagged lots of extra pointless software on it, which apparently is quite annoying because it randomly pop's up warnings and information, although people like us will just disable it with ease.
All 3 have SD readers, only the MBA has a Thunderbolt port according to official spec sheets but some reviews mention that the Samsung has one so we'l have to see on that front.

Personal opinion: both the MBA and the Asus look superior to the Samsung 5, Is the MBA worth approx £100 more? to me yes, but I'm comfortable using OSX.
