DGX Spark OS lifetime?

I think of purchasing 2 DGX Sparks for my office (because a 700+W workstation would be intolerable) for LLM-centric work (inference only, no fine-tuning). I know the OS is based on Ubuntu 24.04. Has Nvidia ever disclosed what is the lifetime of the OS? Meaning, is there a chance they will say people have to get a new product in 2028 and DGX Spark will not be supported?

Edit: Thanks for the replies, I can now feel better dropping 13k euros on 2 Sparks (still not great due to the 273GB/s memory bandwidth but room temperature matters more than peak compute for the buck)
