It's a great design, though Apple put the CPU behind the display so that it is hidden away, then you just have a beautifully simple aluminium stand on the desk. The iMac may have the "chin" but the Studio has the CPU in a box in plain sight. The touchscreen is not going to have wide applicability, which is why this is a professional set up not a consumer one (as reflected also in the price).
It's certainly got the wow factor, but productivity in day to day use is what is key. Windows is still frustrating and you'd have to rip macOS and my favourite Mac apps from my cold, dead hands!
It's great to see other companies catch up with, if not rip off, Apple, and with the Google Pixel phones and this Studio and its intro videos undoubtedly inspired by Apple, it's no surprise that Apple's simplicity of approach can appear a little dated for the fanboys who really want to be wowed.
I agree that Apple are in catch-up territory now on the design side and although their products are solid, they have waned a little. The lack of a substantial re-think of the iMac for years is almost unforgivable. I replaced my last iMac with a 5k Retina version last year, but the design was essentially the same, despite being nearly 5 years between upgrades, and there was only a built-in graphics options.
Apple Watch, it seems to me, has been a substantial and inconvenient distraction from core products.
