I wonder what kind of brightness that 2000 nit screen will actually deliver? Everyone rates their screens on peak, but then SDR is the same 250-350 nit range for most systems.

What's the actual connectivity? USB4? with or without PCIe tunneling? How many ports?

How much is it going to weigh? Battery life? Battery capacity?

DGX Spark desktops idle close to 20w on Linux: that's a lot for a laptop. I'm expecting Nvidia+Microsoft stepped up their driver game some for this release, but it's wild how few creature comforts or nicities DGX Spark came with. Launched with and still has almost no power monitoring or power management capabilities. If you turn on the highspeed NIC it turns into a 40W hotbox even at idle. Nvidia has such a weird mix of supporting what they want to support well, but doing absolutely nothing else. The way Shield TV is still occasionally getting some updates is impressive for example, but it's stayed on an ancient Android version & went a good fraction of a decade without update. Similarly, keeping folks locked on rickety old Linux4Tegra and now DGX Spark heavily modified Linux OSes has been brutal. It's hard to believe this system is going to be much better than a fantastically expensive bag of barely managed idiosyncratic quirks.
