Got mine the other day, and it is mostly great. However, I am having to go through Dell support, as the graphics card fan makes horrible noises when it kicks on. Once this problem is fixed, I look forward to games on it. Until then, I just have to stick with integrated.
Also, my msata drive was configured as a standard drive. If yours it too, and you want it as a cache drive to speed up the system, delete the partition in disk management, them go into the intel utility for drive management (it was already running in the notification area). Then you can enable it as cache.
