Keynote Speaker Chat

Evernote — take notes, add photos, web clips and pretty much any sort of information. You can tag all of your notes and organize them into notebooks. If you turn on syncing, what you add on your computer, iPad or smartphone (iPhone, Android, Windows 7, BlackBerry, Palm) is almost instantly synced to each device. The premium version ($45/year) allows you to share documents with others. You can organize information in notebooks for different tasks and/or use tags to make searching easy.

Newsrack — Great RSS reader. Keep up with all of your Google Reader feeds with easy integration. Beautiful interface that lets you organize feeds in folders or categories and allows easy sharing with social networks and services such as Instapaper and ReadItLater. It’s currently iOS only with versions for both iPhone and iPad.

Instapaper — Save articles, websites or blog posts you want to read later. Comes with an easy-to-install bookmarklet that lets you save an article with one click. You can organize content into folders on the web interface. It also integrates with many other mobile apps. It’s currently iPhone and iPad only, but there are apps for other platforms that integrate with Google Reader. If you sync your mobile device regularly, your articles are also available for offline reading.

Dropbox — Easy-to-use cloud storage. It’s free for up to two gigabytes and you can buy additional space, but the fun part is the referral program. For every friend you refer who signs up for the service, you’ll get an additional 250 MB of free storage, up to eight gigabytes. They have free iPhone and iPad apps as well as Android and BlackBerry.

Birdbrain — A great (unfortunately currently iPhone-only) Twitter app that helps you track followers, un-followers, retweets, @replies and other handy stats. It’s free and helps you monitor your accounts on the go.

These are just a few of the thousands of mobile apps — what are your favorites?
