My primary dev environment is in ec2. I don't really care about multiple monitors. It's so convenient.
But on a similar note, I use VS Code's Remote SSH plugin to connect to an EC2 on one monitor and terminal + browser on the other. It's not my primary dev env, but it's great for experiments and side projects.
on my MacBook Air, I use azure data studio to connect to our MSSQL instances if I need a UI view of our database.
