Apple also announced pricing for its 3G + Wi-Fi iPads: 16GB, $629; 32GB, $729; 64GB, $8.29.

The PlayBook will also be available in 16GB, 32GB and 64GB versions, and RIM could potentially undercut Apple in pricing for its HSPA+ and 4G PlayBook. If it does, pricing could become a competitive advantage for the BlackBerry maker.

In typical Apple fashion, the company left out a number of noteworthy facts from its online , one of the most glaring of which is the lack of any information on the iPad 2's RAM. While I cannot say for sure exactly how much RAM will be found inside the iPad 2, one that the device would ship with a meager 256MB of RAM--less than the 512MB found in the current iPhone 4 smartphone.

If that is the case, the iPad 2 and its owners are going to experience some performance "hiccups," to say the least, regardless of just how powerful its dual-core processor proves to be. It's more likely that the iPad 2 has at least 512MB, but Apple's silence on the subject is slightly worrisome.
