2200 bucks for 4050 Laptop level of performance..and it's not even particularly lightweight. The B390 ExpertBook is lighter and faster.

But reaches only 400 nits?
The B390 in the Duo and ExpertBook are 15% faster. This is the slowest B390 laptop so far.
And so the FPS per weight isn't that good, even compared to 4050 or 4060 laptops. But may be it's quieter or sturdier built..but the Apple Air 15" should be well built and it's still larger and lighter.
