Have you ever wondered why guys can be so hot or cold? One minute he's laying on the charm, the next he can't be bothered to respond to a simple text? Well maybe you're different but most women are completely taken off guard by the real reason behind this. Why? Because it's extremely counter-intuitive!   You see, there's one thing men secretly crave above all else... but he will never tell you himself. In fact, this hidden desire makes or breaks any romantic relationship... And not knowing this one relationship secret almost guarantees he will lose interest or find a reason to shut you out. Do you know what it is?

Smarts have largely replaced PDAs, handheld/palm-sized PCs and portable media players (PMP). Improved hardware and faster wireless communication (due to standards such as LTE) have bolstered the growth of the smart industry. In the third quarter of 2012, one smarts were in use worldwide. Global smart surpassed the figures for feature s in early 2013.The development of the smart was enabled by several key technological vances. The exponential scaling and miniaturization of MOSFETs (MOS transistors) down to sub-micron levels during the 1990s–2000s (as predicted by Moore's law) me it possible to build portable smart devices such as smarts, as well as enabling the transition from analog to faster digital wireless mobile networks (leing to Edholm's law). Other important enabling factors include the lithium-ion battery, an indispensable energy source enabling long battery , invented in the 1980s and commercialized in 1991, and the development of more mature software plats that allowed mobile device ecosystems to develop independently of data providers. Forerunner Main article: IBM Simon IBM Simon and charging base (1994) In the early 1990s, IBM engineer Frank Canova realised that chip-and-wireless technology was becoming small enough to use in handheld devices. The first commercially available device that could be properly referred to as a "smart" began as a prototype ed "Angler" developed by Canova in 1992 while at IBM and demonstrated in November of that year at the COMDE X computer industry tre show. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. In dition to placing and receiving cellular s, the touchscreen-equipped Simon could send and receive faxes and emails. It included an dress book, calendar, appointment scheduler, calculator, world time clock, and notep, as well as other visionary mobile applications such as maps, stock reports and news. The IBM Simon was manufactured by Mitsubishi Electric, which integrated features from its own wireless personal digital assistant (PDA) and cellular rio technologies. It featured a liquid-crystal display (LCD) and PC Card support. The Simon was commercially unful, particularly due to its bulky factor and limited battery , using NiC batteries rather than the nickel–metal hydride batteries comm used in mobile s in the 1990s, or lithium-ion batteries used in modern smarts. The term "smart " was not coined until a year after the introd uction of the Simon, appearing in print as early as 1995, describing AT&T's Writer Communicator.[non-primary source needed] The term "smart" was first used by Ericsson in 1997 to describe a new device concept, the GS88. PDA/ hybrids Main article: Personal digital assistant Beginning in the mid-late 1990s, many people who h mobile s carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, Newton OS, Symbian or dows CE/Pocket PC. These operating systems would later evolve into early mobile operating systems. Most of the "smarts" in this era were hybrid devices that combined these existing familiar PDA OSes with basic hardware. The results were devices that were bulkier than either dedicated mobile s or PDAs, but allowed a limited amount of cellular Internet . PDA and mobile manufacturers competed in reducing the size of devices. The bulk of these smarts combined with their high and expensive data plans, plus othe r drawbacks such as expansion limitations and decreased battery d to separate standalone devices, generally limited their popularity to "early opters" and business users who needed portable connectivity.
