Factors Influencing Consumers’ Laptop Purchases

...FACTORS INFLUENCING CONSUMERS’ LAPTOP PURCHASES Dr. V. Aslıhan Nasır, Sema Yoruker, Figen Güneş and Yeliz Ozdemir Bogazici University, Istanbul, Turkey ABSTRACT The rapid developments in IT sector accompanied by increased competition and acquisitions and mergers in the market, lead both academicians and practitioners to concentrate on the consumers’ purchase decisions in portable PC industry. The NDP group’s report published by PC World state that in May 2003, U.S. retailers made more money selling laptop/notebook computers than they did selling desktops. It was the first time that laptops have outsold desktops in the U.S. This research seeks to develop a better understanding of the factors influencing consumers’ laptop purchases. What makes this study distinctive from other sectoral studies is that, this research also seeks the differences among three consumer groups (stayers, satisfied switchers, and dissatisfied switchers) of a company with respect to the factors influencing consumers’ laptop purchases. It is found that core technical features, post purchase services, price and payment conditions, peripheral specifications, physical appearance, value added features, and connectivity and mobility are the seven factors that are influencing consumers’ laptop purchases. Furthermore, price and payment conditions factor shows significant difference among three consumer groups of a company’s customer base. INTRODUCTION There are seminal studies on consumer......

...that capacity? Is a keyboard enough, or should I splurge for the touchpad/keyboard combo? Do you have any that aren’t this heavy? These are all question I heard from consumers who were looking to buy a new laptop. Laptops have become a necessity to many these days. With a technological world that is rapidly expanding, desktops have become out-of-date, and consumers are demanding laptops with grand capabilities fit into a small package. The vast amount of options out there give consumers a variety of options to choose from. Consumers demand different qualities from their laptop whether it is processing, durability, battery life, display, and a variety of other options. This paper will discuss the present displays being used in stores to promote the products, what consumers voice in terms of what they want in a laptop, and primarily what brands can do to further help their sales. For this specific paper, I will be looking at Dell as the targeted brand. Dell was once the dominant presence is the computer industry, but their market share is diminishing constantly. My goal in this research is to determine what Dell is doing wrong if anything, and what they can do with their brand and products to regain their lost market share. The first store I stopped out to see their laptop display was Best Buy. Best Buy is one of the leading electronic stores in the nation, and is on the market as one of the top retailers that consumers shop at for electronics. The clerks there are tech......

Guangming Ling and Brent Bridgeman Educational Testing Service To explore the potential effect of computer type on the Test of English as a Foreign Language–Internet-Based Test (TOEFL iBT) Writing Test, a sample of 444 international students was used. The students were randomly assigned to either a laptop or a desktop computer to write two TOEFL iBT practice essays in a simulated testing environment, followed by a survey of computer experience. The survey results suggested that the participants had extensive experience using computers, had more experience with laptops than with desktops, and preferred using the laptop computers to the desktop computers. The computer type (laptop or desktop computer) was found to have a negligible effect on essay performance (essay score, essay length, and writing speed). However, other factors, including gender, regional background, daily experience with laptop or desktop computers, preference for a particular pointing device, and previous TOEFL experience, were found to be significantly related to essay performance but did not interact with computer type. Keywords: computer type effects, desktop, e-rater, essay length, essay score, laptop, writing speed INTRODUCTION When large-scale computer-based testing began in the early 1990s, testing centers were......

Assignment1 Individual vs Group Buying Behaviour

...behaviour ASSIGNMENT 1 ROBIN KARUMBA STUDENT ID: 18331141 WORD COUNT: 1450 EXCLUDING REFERENCE Introduction The consumer buying behaviour varies from one customer to another. (Graves 2013) states that it is difficult understanding human emotions effect on the buying decision process yet because we humans have very similar neural wiring we tend to make similar mistakes what he calls ‘mind gap’. This is what leads us to walk out of a shop believing we bought what we wanted. This study will attempt to understand behavioural difference between individuals and group consumers based on influence from various environmental factors. This raises the need for consumer behaviour analysis using a nominated product buying decision process. In this research I’ll use my past experience in the purchase of a laptop for university purpose and a large quantity of laptops for an organisation I worked for. This document this will be categorised into individual and Organisation buying decision process The Individual Analysis * Understanding the customer: influences Personal and Social To get an accurate individual analysis, it is important to understand the consumer demographics and background that influences the decision process. The Organisation * Understanding the customer: influences Buy class and product type The organisation is a multinational food and beverage industry operating in east and south of Africa.

Company’s History and Growth Through the years Dell went from producing PC’s to software, hardware, workstations, electronics, printers, tablets, mobile devices networking, storage devices, servers, security products and other electronic devices and information technology systems but it all started with just building computer systems. Dell doesn’t just sell products to personal consumers, Dell also targets government, healthcare, education and small and large corporations. Michael Dell founded Dell Company; hence the name of the company derived from his family name but the company wasn’t known as Dell back in 1984 when it was founded. In 1984 the company was known as PC’s Limited which designs, manufactures and sells technologies that has a dedicated founder who left his university to commit his time and effort for the company. What separated Dell from other firms in the industry in 1985 is their unmatched service for their customers in their first PC, “Turbo PC” (Dell 2012).

Cia Assignment for Company A and Company B and splits his time between both with his laptop. Bob physically works from both offices and needs to access resources on the Active Directory domain of each company. Unfortunately, no trust relationship exists between these two domains. The IT staff has developed three possible solutions and they want your input (as an Information Security Analyst) on which is the most ‘secure’. Solution 1. Set Bob up with a network account under each active directory domain: have him log in to whichever one he needs access to at the time. Although he may be physically working from Company A, he will likely still need to access resources from Company B and vice versa. Solution 2. Create a local profile on Bob’s laptop and have him manually map to the resources he needs access to and set his passwords to never expire on both domains. Solution 3. Because Company A and Company B are both bound by internal and industry regulations regarding maximum password age, a third (hybrid) solution was developed. This involves Bob working from a local profile (as seen in solution 2) but having to log into each domain once per password cycle to change his passwords before expiration. In this scenario, the best solution that allows a greater amount of availability and a relatively higher level of security would be solution 3. Granted that Bob would follow other protocols and secure his laptop at all times, this solution will allow him to access to his files readily......

We believe that the adults will want to invest in their child’s future, as well as buying a well-made piece of technology for an inexpensive price.   Table of Contents Introduction 4 Part 1: Market Audit and Competitive Market Analysis The Product 5 The Market 7 Part 2: Preliminary Marketing Plan Marketing Objectives 9 Product Adaptation or Modification 11 Promotion Mix 13 Channels of Distribution 16 Price Determination 18 Appendix 20 References 21 Introduction The purpose of this marketing plan is to reach out to children who work on the coffee farms.
