I'll second the surfacebook love. Was using an Asus ultrabook before this and the surfacebook(i7, discrete GPU) has just a bit more oomph that I needed.

Build quality is outstanding, tablet is great for browsing on the sofa and multi-pressure pen is awesome for photo editing. Chews through heavy compiling/development very well. Decent gaming for what it is.

I feel like Microsoft was trying to do the whole tablet PC back in early 2000s and I think that the surface book is the actual realization of what they were trying to achieve.
