Google Chrome is a browser that you can use regardless of whether you use a Mac or a PC.  If you login from multiple devices the same browsing history, apps, and extensions will be available to you.  Personalize your browser with backgrounds, apps and extensions.  

The image above shows some of the apps that you can download into Google Chrome.  Go to the Google Store for more options. Putting them in Chrome lets you launch them more quickly and easily.  Here are some I recommend:

Evernote

Pandora

Picasa

Amazon 1Button

Coloring Pages

Lucas' Whiteboard

Google Play

In the top right corner you can see some of the extensions that you can download from the Google Store. Here are some that I recommend:

The Pinterest Pin It Button

Google Mail Checker (displays the number of unopened mail)

Evernote Clearly (removes side bars)

Evernote Clipper (clips content to Evernote)

Pandora Sound Control (turns Pandora on and adjusts volume)

You Tube Options (removes advertising from You Tube)

AdBlocker (blocks out ads)

Black Menu for Google
