When you combine a Xeon with a DC SSD you end up with a different machine. As mentioned elsewhere, Intel is shifting towards making their Xeon line of processors more available in laptops. That will greatly improve certain activities on a computer. Continued miniaturization of data center class SSD could deliver yet another speed up. Intel’s Ultrabook design may be the dominant form factor for most machines for office level and moderately intense workloads. Future versions may approach thickness no higher than a slice of cheese. More intense workloads will still need a higher end machine such as the HP ZBook but with a Xeon processor. As 2016 approaches, work on 3D XPoint will see a new storage technology that make even more of a difference in high-speed machines.
