This laptop design approach is a very powerful virtualisation (KVM/VM) tool for taking on the road.
Multiple Operating System environments simultaneously running
It is ideal for system administration personnel enjoying VMs and acting like a pseudo server, who need to take it all on the road in a laptop. Surprisingly, the solution comes from a high performance gaming market solution, because of the need to have lots of memory, as well as lots of disk storage running safely in RAID-1 as well as a third internal archive reference drive. This has worked well with the sub-10 seconds quick boot time of Debian, whilst also enjoying access to a Windows environment running within a powerful open source Linux/KVM host.
