I'm hoping for Servo-based alternative to Electron. If it could deliver some performance/memory improvements it would be good advertisement for the project, and also for Rust.
Not sure if that's realistic, Servo app ran on macOS takes about 200MB of RAM usage.
Servo isn't going to use any less CPU than other rendering engines, it will just be able to increase user-visible performance significantly by reducing latency by making better use of multiple cores.
