1981年由亚当·奥斯本（Adam Osborne）发明，第一台笔记本电脑售价为1795美元，命名为“Osborne-1”。捆绑价值1500美元的计划，没有人意识到，在其存在的二十年里，它将开始面临来自平板电脑，智能手机和其他小型移动设备等其他设备的威胁。尽管笔记本电脑市场增长缓慢，但几年之内，其他移动设备（如智能手机和平板电脑）将超越笔记本电脑和个人电脑的增长率（苹果成为最佳Windows笔记本电脑，2014年）也就不足为奇了。然而，eweek.com的报道似乎是部分正确的，只侧重于苹果，这可以根据国际数据公司（IDC）提供的事实来分析。 IDC被认为是市场情报，咨询服务和与IT，电信和消费技术市场相关的事件领域的领导者之一。根据IDC进行的研究，它清楚地表明，在销售笔记本电脑和台式机的零售商中，信心在过去的4-5年里迅速恶化。下表是近三年来全球五大笔记本品牌的销售纪录。根据报告可以清楚地说，笔记本电脑的销售在过去三年中一直在持续下滑。例如，2011年笔记本电脑总销量为4280万台，2013年降至4080万台，另一个主要变化是领导地位，可以清楚地看到，惠普如何从联想的高端位置中被取消。

a)Overview of the topic
Invented by Adam Osborne in 1981, first laptop was priced at $1,795 and named ‘Osborne-1’. Bundled with programs worth $1,500, no one realized that with two decades of its existence it will start facing threat from other devices such as tablets, smart phones and other smaller mobility devices. Despite of marginal growth in laptop market, it will not be surprising that within few years, other mobility devices such as smart phones and tablets will surpass the growth rate of laptop and personal computers (Apple Makes the Best Windows Laptop, 2014). However report from eweek.com seems to be partially true and is focused only on Apple, this can be analysed on the basis of the facts presented by International Data Corporation (IDC). IDC is considered to be one of the leaders in the field of market intelligence, advisory services, and events related to IT, telecommunications and consumer technology markets. Based on research conducted by IDC, it has clearly indicated that confidence among the retailers associated with selling of laptops and desktop has deteriorated rapidly over last 4-5 years. Below table represents past three years, sales record of top 5 laptop brands in world. Based on the report it can be clearly said, that how laptop sales has been falling continuously over last three years. For example, total laptop sales in 2011 was 42.8 million where in 2013 it reduced to 40.8 million, another major change was in terms of leadership position, it can be clearly seen that how HP was removed from its top position by Lenovo.
