The Surface Studio is like one of those fashion show dresses. Stunning and interesting, but what about practical relevance? So its a computer for designers and content editors and I can imagine that they way its set up is great for those tasks. Until we see that there is no SSD option. Are those professionals supposed to work from a way slower HDD only? Well, ok, I guess they could work from their enterprise-level SAN storage, or at least using their fast external RAID array. Oh wait a moment, they can't even connect to it properly. USB 3.0? Not even USB 3.1?
SAN via USB? I don't think so. Network device. Gigabit ethernet to client. Fiber to database servers which are gigabit ethernet to clients. Same with Raid array in a NAS.
