more on your mobile device beyond a browser that can access the cloud.
Can browser widgets provide enough functionality that you don’t need
applications on your device? What if you could get everything you need
accomplished using simple widgets that leverage your mobile device-based
browser to access the cloud? The potential impact on enterprise mobility is
huge. While organizations are deploying more and more Software-as-a-Ser-
vice (SaaS) applications, there is no reason mobile workers can’t access those
applications from their mobile devices, assuming they have enough band-
width (i.e., 3G- or 4G-capable devices). All that is really required beyond
such bandwidth is a browser that can actually handle all of the various SaaS-
associated web standards. Imagine a future environment in which mobile
device manufacturers will partner with multiple SaaS vendors to provide
enterprises complete cloud-based computing solutions that work anywhere.
9.2 What Is a Smartphone?
The deﬁnition of a smartphone is not standardized and varies depending on
who you ask. For most users, the consensus is that a smartphone is a mobile
device that offers advanced capabilities beyond those offered by a typical
mobile phone. Modern versions come with PC-like functionality. Many of
the newer models have customized operating systems and associated soft-
ware that provides a standardized interface. Nearly all smartphones have
advanced features such as email, Internet access, instant messaging, etc.
Smartphones are much more than just another cell phone. They provide
instant access to the web, which translates into immediate collaboration
capability. Whether you are researching ﬁnancial news to predict the stock
market or looking for the perfect golf course to treat your client, it’s on the
Internet. Most smartphones allow you to sync data with your desktop com-
puter. You can store and work on documents from your smartphone, and
you can receive and reply to emails as they arrive in your inbox using real-
time push email.
Smartphone applications may be developed by the manufacturer of the
device or by any other third-party provider or developer capable of accessing
the open source operating system. Other functionalities might include an
additional interface such as a miniature QWERTY keyboard on the touch
screen, built-in video and camera features, contact management, built-in
navigation software, ofﬁce document processing capability, and software for
playing music and viewing video clips. Such smartphone capabilities trans-
form the common cell phone into a mobile multimedia platform for your
