Not a sophisticated use case but I built a fun service to send handwritten notes to my Pi agent from my eink tablet. It leads to a very satisfying and "slow" workflow.

I'll be sending architecture diagrams to my agent, I draw those much faster than I talk. I hope there's a good way to get alerted for agent waiting for your turn. Hmm I wonder if the Claude Code app will install on my Boox. I've been finding it fun to run Claude on weird things, if it runs linux there's a good chance. My favorite install was into my Steamdeck to debug some button sensitivity issues.
