Google's Chrome Web Store is now live. The web-based online app store, similar to the apps store found in iTunes, features cloud-based apps, extensions and themes that you "install" in your Chrome browser (version 8).
The storefront is arranged in a grid, with a sidebar on the right featuring the Top Paid and Staff Picks. On the left hand side are the categories, classifying apps into groups such as Games, Utilities, Entertainment, etc.
Among the (free) apps that I installed so far are Plants vs. Zombies, The Onion New Network, and Aviary image editing app. The installed apps are accessible to the home page when you open a new tab in Chrome.
