...Smartphone Good afternoon to Mr. Frankie and all my friends. Before I get started with my topic, I would like to share a story on how important it is to have a smartphone. The story begins when Ali and Abu went to the zoo. As they passed by the dolphin park, Ali asked Abu, “which animal group dolphins in?”. Then, Abu said he was not sure about that. Ali replied “its okay, I bring along my smartphone.” However, Ali did not search about the animal group. Instead he threatened Abu; he will beat Abu using his smartphone if Abu did not answer his question. My topic for today is the Smartphone. What do you know about smartphones?

...NEW PRODUCT DEVELOPMENT On Apple’s New Product Development Strategy Posted on January 1st, 2010 by daniel Michael Malone from ABC News wrote an interesting article on Apple’s iPhone and its overall new product development strategy, with interesting strategic lessons for new product development and business in general. Google Nexus Offers Little Competition to Apple iPhone Why Google’s New Smartphone Won’t Knock Apple Off Its iPhone Throne COLUMN By MICHAEL S. MALONE, ABC News Jan. 1, 2010 Whether the marketplace is ready or not, the Big Guns in consumer electronics are about to make their move at the dawn of the New Year. Next Tuesday, Google is expected to announce its long-rumored Nexus One smartphone. It is undoubtedly designed to run the Google Android operating system for cellphones, which the search giant introduced more than a year ago. Android was envisioned as a major breakthrough in cellphones because it offered an "open" operating system i.e., one that other companies could use and design applications for. At the time, this strategy was compared to that of Microsoft Windows, which broke the market hegemony of Apple’s decidedly non-open OS in the mid-1980s and within a decade, turned Apple into a niche company. This time around, the new Android phones were supposed to break the hegemony of the Apple iPhone. So far, it hasn’t quite worked out that way with Android. A number of cell phone companies notably Motorola, HTC, and Samsung have adopted Android...

...Smartphones and Younger Generation In 2011, Tim Pike discussed the increasing amount of younger generation using smartphones nowadays in the article “How smartphones technology affects society.” (Pike, 2011). Pike wrote: “The advantage of a smartphone is the advent of fastest connection and a transfer speed, which means; potentially children can always be instantly connected”. In other words, smartphones help parents be aware of what children do, tighten the connection between parents and children, and increase their safeness wherever they are. Personally, I disagree with the author’s point that with the common of smartphones using, children could be safer with a smartphone and could be connected immediately. It is true to say that smartphones help people communicate instantly, no matter where you are. However, it is not necessary for a child to own a smartphone. In fact, it is not safe at all to have a child separated from their parents, go on their own and have a smartphone to contact to their parents. They always need to have adults with them if their parents busy and couldn’t take care of their children. Following a recent survey lead by mobile service provider Zact found that 56% of 10-to-13-year-old children own a smartphone, 25% of 2-to-5-year-old children also have a smartphone. It’s not reasonable and sensible to give children a smartphone in that age if they are accompanied by the adult. Smartphone will disrupt the bond between children and parents more than help...

...A smartphone is a high-end mobile phone[1][2][3] that combines the functions of a personal digital assistant (PDA) and a mobile phone. Today's models typically also serve as portable media players and camera phones with high-resolution touchscreens, web browsers that can access and properly display standard web pages rather than only mobile-optimized sites, GPS navigation, Wi-Fi and mobile broadband access. The term smartphone is usually used to describe phones with more advanced computing ability and connectivity than a contemporary feature phone, although the distinction can be vague and there is no official definition for what constitutes the difference between them. The definitions also shift over time since many phones that are considered feature phones today can have capabilities that exceed those of phones that had been promoted as smartphones in the past. Smartphones run mobile operating systems such as Apple's iOS, Google's Android, Microsoft's Windows Phone 7, Nokia's Symbian, RIM's BlackBerry OS, and embedded Linux distributions such as Maemo and MeeGo. Such systems can be installed on many different phone models, and typically each device can receive multiple OS software updates over its lifetime. Smartphones run third-party applications using advanced application programming interfaces (APIs),[4] which can allow those applications to have better integration with the phone's OS and hardware than is typical with feature phones. In comparison, feature phones more...

Comparing Smartphones

...Case: Comparing Smartphones The two attributes that I find most important in a smartphone are the CPU speed and the internal storage. I believe CPU speed is highly important for a smartphone because that is how fast it will function. The CPU speed is basically the brains in electronics and allows programs to run and operate. Having a fast phone will allow you to carry out your tasks in a timely manner and be able to look up things without crashing. The internal storage is important in a smartphone because it will allow a person to have a lot of data on their phone. It will allow a person to have many files, photos, and videos that all can be stored right on their phone. The iPhone 5 ranks the lowest, according to the selected attributes for smartphones. It is the most expensive and in every attribute is the lowest except one attribute which is the weight, so it is the lightest smartphone. It is the most expensive at $649 in comparison to the other smartphones being priced ranging from $449 to $579. That makes the iPhone 5 about $100 more expensive, yet it is basically the lowest ranked with respect to the selected attributes. In some attributes like CPU speed and the megapixels of the camera it is close to the other phones listed. According to the table given with attributes of smartphones I believe that iPhone 5 is not well positioned compared to the competitors. The iPhone 5 is the lowest ranking in every category listed except for the weight of the phone itself...
