Can I suggest you learn something about a domain before commenting on it?
Photo editing can be hugely resource intensive. Camera RAW files have been getting larger over time, and all but the simplest edits demand an SSD, a fast processor, and at least 32GB of memory. 128GB isn't unusual for commercial work.
You can get by with less, but sooner or later - usually sooner - you run out of RAM and your machine starts thrashing.
Many Photoshop features are hardware-accelerated, so having a good graphics card makes a significant difference to editing speed.
3D animation definitely needs a good graphics card. So does video editing.
Audio doesn't, but it needs as much raw processor power as possible. I know DJs/producers who are running dual 12-core Xeon systems for their mixes, and adding PCI DSP cards on top.
Surface Studio looks very nice, but it fails to tick most of these boxes. The reality is there's a significant market for creative power users willing to pay good money for multicore server-grade towers for their work.
Neither Apple nor MS are paying attention to this market. The Mac Pro is an underpowered curiosity now, and Surface Studio has - sadly - been hobbled by greed and penny pinching.
