Here’s a quick overview of Mission Control and Launchpad in OS X Lion, Apple’s upcoming major update to OS X.
Mission Control is like Expose, Spaces and Dashboard on steroids: Hit a hot corner and all the open windows fly away. You then get an overview of all the running applications, with thumbnails of open windows. There’s also your Dashboard widgets and virtual desktops in Spaces. When it was first previewed by Apple last year, critics said Mission Control was a mess, but I think it’s pretty good. It works really well. It’s much clearer than Expose, and I can see it becoming a central part of my workflow.
Launchpad, on the other hand, won’t be. Launchpad is like the Home screen on the iPad. Icons for all your apps are displayed in a grid. But it suffers from the same problem as the iPad — it’s hard to find the app you’re looking for among the clutter. Much easier to launch a search. Same in Lion.
