A recent video demonstrates strengths that Blackberry's new tab PC has over the iPad in web browsing: faster loading times and flash support (i.e. animated web pages, for example).
One article suggests that the Blackberry's double the horsepower in internal hardware simply outshines what the iPad has under the hood. However, it goes on to say, the iPad might have improved by the time the Blackberry tablet comes out, which is still a ways away.
What's still at stake, however, is the screen-size quandary: are customers looking for an amazing new handheld device more like a blown up cell phone or more like a mini-laptop? I'll admit that the size of the screen is tied for #1 on reasons why I might choose iPad. Reason #2 is the apps.
Now what I need to see is a competitor show me that the software on a 7" screen makes it all worth my while.
