On the top screen you see Windows Editor running on Windows 11 24H2 and a ThinkPad Z13. The bottom screen shows Windows Editor on Windows 11 24H2 and a Yoga Copilot+PC. Both are on Windows 11 Insider and Editor has the exact same version.
On ThinkPad Editor has a Copilot icon which offers some rewrite functions. It sends the text to the Microsoft Azure cloud for processing and deducts from the Copilot credits.
On Yoga Copilot+PC this icon is missing, and you cannot use these rewrite functions in the cloud nor locally, even though Copilot+PCs are advertised as being superior because they can run AI right on the machine.
I love this Yoga notebook with its superior performance and battery life, but Copilot+ it is not. This feels more like Copilot-.
This is simply a huge marketing SNAFU. Shower partners with money so that they build powerful Snapdragon-based PCs, then force a special Copilot-button on them and finally ask Enterprise IT admins to remap this button to launch the Microsoft 365 app.
