maxleibman, I got my Surface Laptop Go onto the Windows Copilot preview. Not especially earth-shaking. Basically, it's the Bing Chat sidebar from Microsoft Edge, but on Windows itself.
I DO like having this interface available outside of the browser, and having a keyboard shortcut key to summon and dismiss it (it takes over Cortana's former Windows Key + C), but otherwise I haven't seen it do any tricks I haven't already seen from ChatGPT and Bing.
