RIM shipped just in the second quarter, down from 500,000 last quarter, when it started selling the tablets. The company didn't say how many of the 700,000 tablets sold reached consumers' hands, and not store shelves and depots.

Despite for the PlayBook, the company promised a software update in October that would fix the main shortcomings of its tablet. Overdue since this summer, the PlayBook software update is set to finally include native email, calendar and contacts capabilities, as noted by .

The PlayBook was at launch over its lack of a native email client, along with other related to the QNX OS running on the tablet. PlayBook owners have had to stay tethered to their BlackBerry phones for the functionality they haven't been getting on their tablets.

The Android App Player should also debut in the upcoming PlayBook update, which, as the name implies, would allow users to run applications designed for Google's Android OS. Even when the PlayBook will be able to run Android apps, it's unclear why users wouldn't just opt for an Android tablet instead.

To add more punch to the PlayBook, RIM would also launch a BlackBerry Video store with some 10,000 movies and TV shows available to buy. PlayBook's display is only 7-inch, but the tablet has an HDMI-out port, so users would be able to play these videos onto their TVs as well.
