I’m a recording engineer/mixer/producer. I use my V for travel only. My main computer is a home-made desktop I built from readily available state-of-the-art components. An AIO is not for me. I cannot afford downtime that would come with an AIO screen failure, ps failure, etc. And, I need many drives, video cards, audio features, and connectivity, cooling, that AIO’s cannot match. If it needs to be fixed, I fix it the same day, with easily available components.
I purchased a fancy ASUS AIO for my wife, she is not a computer geek, and she loves it. It’s an I7 with an SSD and a hard drive, She has a HP Spectre laptop for backup. I believe a backup is necessary for an AIO if you business depends on uptime. FWIW her Asus does not cost nearly as much as a Surface, with specs that are similar, but it does not fold flat. It may be a reasonable model for EVE. Asus makes some of the best motherboards.
Price would depend on options. I would want 27", 4k, touchscreen, a current i7, non glare, easy access to drives, accurate color, and a modern graphics card (not stock). Less than $2000.
