Research in motion has just released some details about their new tablet called the Playbook. As suspected, the Playbook is available in 16GB, 32GB and 64GB versions. The 7 inch Wi-Fi device is priced to compete with the iPad2, matching the same prices per GB of storage, but is smaller than Apple's 9.7 inch device. It might be a tough entry into the market for RIM trying to catch up with Apple and the proven success of its iPad models. From what I've read, the Playbook doesn't contain a dedicated email, contacts or calendar, as the iPad does.
Further concern for both RIM and Apple, might be Samsung's 8.9 inch Android Honeycomb Tablet, which will be selling for less than the two previous devices. Or, matching Rim and Apple's price, the 10.1 Galaxy Tab is larger and thinner yet!
Just as the smartphone industry competition started heating up a couple of years ago (with iPhone, Blackberry and Android) now the tablet market is doing just the same. It's interesting how RIM, Apple, Google and others are able to create a device and the competitive market so quickly!
