Although the device hasn't launched yet, many prospective customers believed the PlayBook's greatest weakness would be its lackluster app selection, especially when compared to the ecosystems Apple and Google have established. Eradicating those concerns, RIM will demo the new app players and the BlackBerry Tablet OS SDK at BlackBerry World in Orlando, Florida from May 3 to May 5. The PlayBook is slated to launch in North America on April 19 with models ranging from $499 for 16GB of internal storage to $699 for 64GB, or about the same pricing as Apple's second-generation iPad.
