I have a 10" 1366x768 netbook. The screen itself is ~150DP, and with Windows running at default DPI settings, small text is borderline too small to read if it's sitting on my knee. People with poor vision will have to hold it closer than normal or change the DPI setting in windows (at which point they might as well have bought a 1024x600 model anyway) resulting in a poorer user experience.
I like the higher resolution; but I'm not surprised that it has never been more than a tiny niche in the market. IIRC it's been several years since anyone has released a 10" model at that resolution. Although with Windows 8 requiring a minimum of 1024x768 to run and 1366x768 to run two metro apps side by size this might change in the future.
