Microsoft Outlook for iPad

Here's another option for accessing your email accounts from your iPad.  In addition to Microsoft's email systems, you can also define Apple iCloud, Google Gmail and Yahoo Mail accounts.  While I personally like the Divide app to separate work and play, the Outlook app has a nice look and feel, better swipe gestures and a cool feature that allows you to easily send times you're calendar is open, so finding meetings times becomes less a chore.

There's an Android version available for preview, but it appears a bit buggy at this time.
