The DGX Spark seems to have one intended usecase: local AI model development and testing. The Strix Halo is an amd64 with iGPU, it can be used for any traditional PC workload, and is a reasonable local-ai target device.

For me, the Strix Halo is the first nail in the coffin of discrete GPUs inside laptops for amd64. I think Nvidia knows this, which is why they're partnering with Intel to make an iGPU setup.

I think it's beyond that even - it's for local AI toolchain model development and testing or those people who have a ore-exisitng nvidia deployment infrastructure

It feels like nVidia spent a ton of money here on a piece of infrastructure (the big network pipes) that very few people will ever leverage, and that the rest of the infrastructure constrains somewhat.
