Just tell me what it does better than the iPad...that's all I need to know.
From online sources:
Overall, it looks like the new PlayBook might be offering just the options a lot of people who have snubbed the iPad in favor of a real laptop have wanted. Of course, the coming iPad 2 will be expected to have front and rear facing cameras for video calling as well, but we haven’t seen Apple officially announce the model yet. Furthermore, that huge 1 GB of RAM in the PlayBook is 4x of what the current iPad has. While I will expect the next iPad to have at least 512MB of RAM like the iPhone 4, it isn’t a sure deal yet. I also really like the microHDMI and microUSB support the PlayBook has.
Apple's iPad has the biggest screen here, a 9.7-inch LED with IPS technology (for a wider viewing angle) and a 1024x768 resolution. The BlackBerry has a smaller 7-inch screen, but the pixels are more densely packed to deliver 1024x600 (WSVGA) resolution. Both displays are capacitive touch screens with full multi-touch and gesture support.
The BlackBerry PlayBook has the most memory here, a full gigabyte compared to Apple's 256MB. When multi-tasking arrives in iOS 4.2 that quarter gigabyte may turn out to be a little on the low side.
The iPad doesn't have any cameras but the BlackBerry ups the stakes with a 3MP front facing and a 4MP rear facing camera that's capable of 1080p HD video recording.
Unless there's an outbreak of silly pricing BlackBerry's PlayBook is the best tablet here - on paper, at least. It has the best processor, the most RAM, the best cameras and the newest operating system.
