Part I: Getting Started
The final dimension is the application itself, or more precisely, how the user
interacts with the application. The Multi-Touch user experience sets it up so
that the user is naturally more connected to the device — there is no mouse
or keyboard acting as an intermediary — and what’s more, Apple promotes
the use of gestures as much as possible rather than the use of controls. If you
want to move a map annotation, don’t show arrow or direction controls or
force the user type in a new address (although sometimes that may be the
way to go) — let the user drag it to where she wants it to be, and provide
feedback along the way.

The iPhone allows an immediacy and intimacy as it blends mobility and the
power of the desktop to create a new kind of freedom. I like to use the term
user experience because it implies more than a pretty user interface and nice
graphics. A compelling user experience enables users to do what they need
to do with a minimum of fuss and bother. But more than that, it forces you to
think past a clean interface and even beyond basic convenience (such as not
having to scroll through menus to do something simple).

Compelling Content in Context —
What the App Does
There are a lot of different kinds of applications on the iPhone, ranging from
Utility applications like Weather to communication-heavy ones like FaceTime
to others that connect you to information and computing power on the Web
or even to social networking communities.
Utility applications like Weather to communication-heavy ones like FaceTime

or even to social networking communities.
These applications shine when they enable you to do what you’d never want
to do on the desktop (or even a laptop), either because you don’t have the
hardware or because, even if you did have the hardware, doing it that way
would be way too inconvenient. (The added bonus to such applications is
that they’re available no matter where you are.)

Imagine being at Heathrow, dead tired, taking out your laptop in the middle
of a crowded terminal, powering it up, launching the application, and then
navigating through it with the touchpad to get the information I got easily
while holding the iPhone in one hand. I want that kind of information quickly
and conveniently; I don’t want to have to dig my way to it through menus
or layers of screens (or even going through the hassle of finding a wireless
Internet connection). Seconds count. By the time any road warrior tied to a
laptop did this at Heathrow, I would already be on the Heathrow Express.

And don’t forget games and other pieces of frivolous (that’s the point) enter-
