Positioning is key.
Marketing. Positioning. Put two and two together and you get success. (Generally Speaking)
Apple’s Ipad was the first of its kind. A tablet that brought functions such as multimedia, web browsing, gaming, and productive applications all within a 9.7 inch display.

Blackberry has recently released their own tablet. A very powerful device, that on paper, is superior the the Ipad. (However, the Ipad is the first generation model and it is expected that Apple will be releasing a 2nd generation Ipad for 2011.) The Playbook is set to be released sometime in 2011, and is already being considered a serious competitor for the Ipad.
Apple’s marketing campaign emphasizes that they have revolutionized how we use technology in our everyday lives, and that it is only going to improve. When thinking of a device like the Playbook and Ipad, most people think of an Ipad before the word tablet. Even if the Playbook has better technical specifications, Apple is already a better known brand with regards to tablets.
Apple’s positioning provides a difficult entrance into the consumers mind for products like Blackberry’s Playbook. Apple’s product is the first of its kind, and first in a consumer’s mind.
