BlackBerry's native email application and instant messaging support are arguably they two key features to RIM’s success in the smartphone market. You'd think the company would leverage these strength with the release of their first ever tablet, the BlackBerry PlayBook, but apparently they won't even be present at launch.

According to a leaked internal document, The PlayBook is slated to launch in the U.S. and Canada on April 19 with the Wi-Fi model that is launching initially priced at $499, $599, and $699 for 16GB, 32GB, and 64GB, respectively, right in line with the equivalent iPad 2 models.
