This! Especially, support for modern laptops is important. Personally, I
don't know many developers who use a desktop PC these days (but I do
respect the fact that many do - old PCs as well). My laptop builds world
in 1h30m which is pretty decent. I don't feel a need at all for desktop
computer and I don't want to trade away the freedom of bringing my
laptop with me anywhere for work.

When it comes to attracting new developers, modern laptop support also
plays an important role. Without new developers coming in, this project
will fade out and die.

Another side of graphics which isn't discussed at all is GPU computing
using technologies like Radeon Open Compute, made possible by the amdgpu
driver with KFD (porting work in progress but not a priority atm).
i915kms has GVT for virtualization of the GPU (porting initialized).
These are pretty serious technologies that could potentially lead to
good business (which is now lost to Linux). Modern graphics support
isn't all about fancy desktops and spinning gears. 

Totally outside the topic of this thread but I felt like ranting a bit....

PS, if anyone want to help develop an iommu driver for amdkfd, please
let us know :)
