The new 2010 iPod Touch has been revealed, including features that were expected but not included on the 2009 model.

4th Generation iPod Touch

At just 7.2mm thick, the new Touch has shed some of its bulk including that rounded back many users complained about. A new microphone is included to support FaceTime, but should also work with other applications on the App Store.

As expected the new iPod Touch is running on Apples A4 processor just like the iPad, iPhone 4, and newly released AppleTV. While Apple doesn’t like to publicize the amount of RAM in iOS devices, the current generation iPhone has 512MB so that would be a safe bet for the iPod Touch.

Apple also gave the new touch a significant screen upgrade: Apple’s Retina display at 960×540 resolution.

Like the iPhone 4, the new Touch also has a 3 axis gyroscope to augment the 3 axis accelerometer already present in earlier models. It does not have a magnetometer (digital compass), something the iPhone has had since the 3GS was released in 2009.

The rear facing camera is able to record 720P HD video at 30 frames per second, and like the iPhone 4, users can upload directly to YouTube or MobileMe, or purchase Apples iMovie app to edit videos right on the device.

The front facing camera, which is a 640×480 standard definition sensor, will support Facetime, potentially opening up Apples new open video calling system to millions of users who don’t have iPhones.

Last year Apple kept the 2nd generation 8GB Touch as an entry level model, however this year Apple is selling the new 4th generation device for all price points, 8GB for $229, 32GB for $299, and 64GB for $399.
