Mobile devices play a far more crucial role in mobile enterprise transitions than desk-bound machines
	in corresponding electronic transitions.
	The ever-increasing capability of mobile gadgets having small and compact sizes is a revolution in
	itself that influences all the dimensions of MET.
	Capabilities of mobile devices need to be correlated to the mobile Internet, mobile contents, and
	wireless network infrastructures so that they are of maximum value to the business.
	Mobile devices are the most crucial aspect of a mobile business. Their processing capabilities
	influence the architecture (thin versus rich client), usability, and security requirements.
	This mobile device usage is given due importance in MET, starting with phone and text usage, through
	to the incorporation of devices in business processes.

	Eventually, mobile devices also become part of the "green mobile" aspects of a business. Mobile
	devices are influenced by both hardware and software factors.
	Mobile system architecture also influences devices; a thick client model will require the devices to run
	sophisticated operating systems and applications.
	For the hardware aspect of mobile devices, it is necessary to consider their physical characteristics
	such as size, weight, ruggedness, and battery life, for example.
	The software aspect includes applications, usability, and operating systems.
	Mobile devices also need support from server-side applications, and are influenced by system
	architectures such as thin client or thick client.

	These two hardware and software aspects of mobile devices and applications are also interrelated.
	Most new mobile applications consume a significant amount of battery power, almost to an extent that users end up charging their devices on a daily basis.
	For example, the sophisticated BlackBerry devices are built on a Java-based operating environment,
	executing Java applications.
	Mobile devices also include Web browsing features, which use Hypertext Markup Language (HTML)
	and Wireless Markup Language (WML) Web pages, and use languages such as .NET, Java, Web Services, C#, and ASP/JSP.
	The areas that a mobile device manufacturer must look into are: Mobile Networks, Mobile
	Applications, Mobile Applications and its technologies, Mobile Web Services, Mobile Groupware, Mobile Enterprise Architecture, Mobile Contents, Mobile Convergence, and Mobile Interfaces etc.

	Device Range and Categories
	These devices include ubiquitous mobile phones, PDAs, wireless laptops; tablet PCs, smart cards, and wireless modems. These modern mobile devices have excellent portability, data security, battery life, and operating time compared to earlier ones.
	Nanodevices
	A significant advancement in mobile devices is their dramatic reduction in size. Mobile devices are moving from micro to nano as the emerging nanotechnology influences their manufacture and use
	Projection Technologies
	Presentation technology currently uses liquid crystal displays (LCDs) that are coupled with touch-screen technologies in smart-phone displays. However, LCDs are increasingly being superseded by organic light emitting diodes (OLEDs), which are lighter and thinner and provide wider viewing angles as compared with LCDs

	Device Convergence
	Device convergence implies convergence of multiple functionalities, services, and related offerings on a single device. It also implies the convergence of mobile devices with supporting wireless network infrastructures, which enables seamless transitions and portability of devices.
	Device Independence
	The device independent group of the World Wide Web Consortium (W3C) started its work with a vision "to allow the Web to be accessible by anyone, anywhere, anytime, anyhow." Due to drop in price of mobiles demand for web access has increased dramatically which provides new opportunities.
	Four Stages in Mobile Device Usage are:

		Stage 1: Mobile devices are used in a routine manner in this stage, that is, for voice calls
		(which are now accompanied with text facilities).
		Stage 2: In this stage, mobility can be incorporated formally in an existing business process to
		generate an entirely new engineered process for the business.
		This usage of mobile devices is more involved, and it may require some training and help.

		Stage 3: This stage involves the innovative use of mobility that allows a business to
		make strategic use of mobile devices. Such usage requires strategic planning, prototyping, and, for large businesses, working in collaboration with the device manufacturers and network service providers.
		Stage 4: In this stage, a business breaks out of the "profit-making" mode and moves toward
		other dimensions such as environmental intelligence and sustainability.
