Separate process: Web apps can hog memory or processor cycles or even bring down the whole browser in extreme cases. By running each app in its own process, we minimize the impact of any mishaps. We can also benefit from operating system tools that less us view the memory/CPU consumption of a specific application.
Minimal user interface: A general-purpose browser UI is not necessary or appropriate for most web apps. It is more efficient to provide a UI that is specific to the application. This also cuts down on UI clutter (hence the term distraction-free browser).
Basic desktop integration: Support of desktop features can make using the app more natural and convenient for end users. This includes the ability to create desktop shortcuts, to place the application icon in the tray or dock and to display pop-up notifications.
Customization: Apps can be run using a shared browser runtime and customized using client-side script (similar to Greasemonkey).
Custom stylesheets can be used to tweak the UI.
