Working on multiple Figma instances while having things like Notion and Slack in the background is a real-life situation for a lot of people nowadays. Even a $3000 MacBook Pro suffers to handle it, but you could easily do it with a 2013 Macbook Air via Mighty. Think of it as renting a new computer. Also most entry-level users have to run these for work/school but can't on cheap hardware.
Yeah, what you're describing sounds like a work station. Maybe Mighty will allow companies to buy super cheap laptops + Mighty for their non-tech folks to get up & running fast?
