1 litre micro PCs are about 4X (35W+) TDP and price of Intel N150 with 6W TDP. They do offer more performance and features (e.g. security) than N150, but exist in a separate and stable (15+ year) category of business desktop.

Mini-PCs have a range of experimental form factors, including mini-desktop, NAS, router, tablet, SBCs, industrial with GPIO, thanks to competition between Chinese and Korean (e.g. ODROID) OEMs.

HP has a $220 4GB Windows laptop and $400+ 8GB Chromebook based on Intel N150.
