I bought the Snapdragon Elite X over a year ago based on the promises of Qualcomm to bring solid Linux drivers at some point. Fast forward to today, Linux for that SoC is still a hot mess.

Maybe I'm being overly hopeful, but given the DGX Spark only runs Linux, and this is apparently a sibling in a laptop form factor, maybe it won't be too difficult to get Linux up and running effectively? Probably (a lot) more easily than Asahi on Apple Silicon, anyway.

One of the hassles with ARM machines is that you might technically be able to boot Linux on it but your Thunderbolt, display out, wireless, etc. will lack support and not work.

They did put linux on it. https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux
