Whitespace: A tablet computer - not a big phone
The iPad evolved from a phone. The iPad is virtually identical to an iPhone - just with fewer features.
RIM has the opportunity to be the dominant Computer in (as Steve Jobs calls it) the Post PC Era. Building on QNX is a real advantage that no one else can leverage.
In technical terms, QNX is a mature real-time operating system designed to run on embedded devices. It is fast, efficient, technically advanced and robust.
In contrast, Apple's iOS is a phone-oriented task swapper that is remarkably similar to the 1989 version of Windows 2.0.
From the consumer point of view, QNX let's you do many things at once. It's the opposite of the iPad, where focus is limited to mainly one activity.
I like to watch a movie, browse the web and read a book in rapid succession. If you think that's a stretch, just watch a teenager use a computer and you'll get a glimpse of the future. Either way, I have little interest in doing just one thing.
With my PlayBook, 'human directed multitasking' is easy. Videos automatically resume when the player comes into view; and pause when they seamlessly move to the background. I can build up a reading list of web links while listening to music and then switch to a book or two. Trying to do the same on a iPad is an exercise in frustration.
I don't want to go back to 1989 with my tablet. I want to move into the future. And so do my teenagers.
