Boxee announced today that it has released its long-awaited iPad app.

The app comes with the Boxee Media Manager, which allows it to stream videos from your PC to the iPad, as well as a “Watch Later” bookmarklet and firmware for the Boxee Box.

“We built the app to be useful for any iPad user, even those who have never heard of Boxee before, but it has the added benefit for current Boxee Box users that you can send video to your flat screen throught it (we’ll include this for Mac/PC users in the fall update),” says Boxee’s Avner Ronen on the Boxee blog .

The app automatically delivers videos shared by the user’s Facebook, Twitter, and Tumbler friends.

On the “Watch Later” feature, Ronen says, ” Each day, we’re bombarded by video from everywhere. Use the freshly re-designed bookmarklet to, umm… bookmark videos from the Internet and have them waiting for you on your iPad (and anywhere else you’ve got Boxee). Now you’ve got one place to queue YouTube videos, TED talks, FunnyOrDie videos, a TV Show you missed, or anything else you don’t have time to watch right away. It’s an easy way to create a video playlist for the commute, the bed, the couch or the bathroom (this is mainly for Idan, whose iPad we don’t touch).”

There is also a “Featured” feature, which highlights hand-picked content chosen by Boxee’s editorial staff. The screenshot above shows a “Junip” video, so they must have some good taste.

The app also lets you send videos to your TV if you have a Boxee Box. In addition to that, they’ve added an experimental feature taking advantage of AirPlay. You can hit the AirPlay button and see your Boxee Box as one of the target devices.

The app is available in the App Store.
