A Simple Mistake by Apple, That's It!
So Apple can never go wrong right now and we all can see that from the media. I was watching a Cnet video and they said one of the most coveted things that users want the iPhone 5 to have is 4G. Now this may not happen now or anytime soon but one day Apple will release a product and make a mistake, whether it is because they get too comfortable on top or to try and save money, but they will slip up in the future.
Think what would happen if the iphone 5 came along without 4G (I can dream right?). Then apple fans think "Maybe I will wait for the next update". Suddenly they have 6 months on their hands or more without an upgrade and they see that the other phones look pretty good! RIM has their 4G QUAD CORE :D phone out, and it starts getting a little more media support and good reviews. This is what blackberry needs, a slip up (as well as a solid phone and operating system which I believe they will have) where they can get a foot, no scratch that, a toe, nay a baby toe in the door again and win back some customers.
