It’s no secret that “multitasking” is one of the great new features of iOS 4. Unfortunately, many people have a misconception about what Apple has implemented. Hopefully this short essay will help you understand the restrictions and the good reasons for having these limits.
On your desktop, multitasking means that any application or process can run [...]
If you’re like me, the iPad has changed how you look at computers in just a matter of weeks. The possibilities for this device seem endless. It’s natural at this point to start thinking about the future, and to do that thinking in terms of the past.

If you’ve written an application for the iPhone, you’ll eventually encounter a customer problem that you can’t reproduce.
