With a name that sounds like something you'd use at a sporting event, the BlackBerry PlayBook is the latest – and most unique – Apple iPad 2 challenger.

Running a new OS called QNX, with quirky features like bridging to a BlackBerry phone for secure email and an oddly confusing initial setup, the PlayBook is a stark departure from the more iPad-like Motorola Xoom. Business-minded features such as built-in viewers for spreadsheets and word processing files are welcome, and the PlayBook gets extra credit for being fast and nimble on a dual-core 1GHz processor.

Throw in a 3MP front-facing camera, a 5MP rear-facing one, a bright and crisp 1200x600 resolution screen, a light 425g body and all the typical gyro, accelerometer and GPS sensors and you have the makings for a powerful 7-inch tablet.

As we discovered in our first hands on test, the PlayBook is sorely lacking third-party apps, but does show promise.

The powerful multi-tasking, where you can run a video in one window and play a game in another with both apps running concurrently, is a first of its kind for a mainstream tab.

File storage capabilities, support for an HDMI connection for playing 1080p video and a slick interface make the PlayBook an interesting anomaly. Unfortunately, the overall experience can't compete with either the iPad 2 or the Xoom, and even falters compared to the original Samsung Galaxy Tab.

Yet, we're still hopeful that Research in Motion (RIM) will keep working with developers (it gave them free PlayBooks if they created an app) and boost the device out of niche territory.

At $500 (£300) for the 16GB model we tested (there are also 32GB and 64GB versions available), the PlayBook is the same price as the entry-level 16GB Apple iPad 2.
