I've had my Surface Studio 2 for a little over 7 months now and I am pretty happy with it.  It is a beautiful system and I don't regret my purchase.  Be aware that Microsoft has made certain sacrifices on the construction of this system.  The biggest is that they have put all of the components in a very small enclosure.  Because of this, the components are basically similar to laptop components.  In other words, don't expect the same performance as high-end desktops.  I always get a little nervous when running games or applications that are computationally heavy for long stretches of time.  The system will get very hot in these cases.  In some cases I have experienced thermal throttling.  This isn't an issue for 2d art/illustration applications.  (Which is the system's real strength.)  I'm a little disappointed with the N-Trig technology that Microsoft uses for the stylus.  You pretty much have to use some type of software stabilization to compensate for its poor design--you will get jitter otherwise.  Microsoft either needs to improve this technology or ditch it.  The digitizer on my iPad Pro is much better and I didn't pay nearly as much for the iPad as I did the Surface Studio 2!
