据尼尔森最新调查显示，平板电脑正在逐渐取代笔记本、台式电脑、电子阅读器、专用游戏机的地位，为传统的计算机设备制造商带来了极大挑战。

该调查结果指出，35%的受访者表示自从有了平板电脑，他们使用台式电脑的频率大为降低，甚至完全冷落了台式电脑，还有32%的笔记本电脑用户也有同感。这一点也许可以解释PC设备销量下降的原因——市场调研公司IDC的报告曾反映，PC设备在今年第一季度的出货量减少了3.2%，iPad等平板电脑的崛起是这种现象的成因之一。IDC报告认为，平板电脑受到用户欢迎与其售价和使用体验有关。

impact on other devices usage

尼尔森调查表明苹果iPad是平板电脑大战第一回合的最大赢家，有82%用户购买的是iPad，三星Galaxy Tab以4%的比例居于次席。

但受到平板电脑冲击的并不只是PC市场，电子阅读器和游戏机销量也因此受到影响。27%的电子阅读器用户表示，他们购买平板电脑后就很少使用电子阅读器，有四分之一的掌上游戏机用户以及20%的控制型游戏机用户反映，他们已不再像过去一样依赖游戏机设备。任天堂等传统游戏设备公司正面临智能手机和iPad等新型移动游戏设备所带来的威胁（游戏邦注：该公司上一财年的硬件销售下滑，并因此导致其总体营收下降了29%）。

不过有观察者指出，平板电脑仍只是一个新生事物，目前还没有足够的证据表明其他设备的销量走低与平板电脑直接相关，智能手机市场的繁荣发展也改变了人们对其他设备的使用习惯。除此之外，经济不景气也可能是影响其他硬件设备销售的不利外部因素。但无论如何，平板电脑已显示出其强大的生命力，并将继续重塑硬件设备市场格局。

tablet ownership and usage

有77%的平板电脑用户表示，他们使用这种设备执行以前在台式电脑或笔记本上完成的任务，有31%受访者称使用平板电脑的主要原因是它更便于携带，有21%用户的理由是它的界面更友好，还有15%用户表示启动速度快最为关键。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

Tablets Starting to Replace Other Traditional Devices

Tweet Tablets are cutting into desktop and laptop use and are also stealing time from e-readers and dedicated gaming machines, according to a new survey from Nielsen Co. The company found that the rise of tablets has started to shift the computing load away from more traditional machines and now presents a significant challenge to hardware makers.

Nielsen said that 35 percent of tablet owners said they used their desktop less or not at all now, and 32 percent of laptop users said the same since they bought a tablet. This may explain some of  the recent falling PC sales figures; IDC said PC shipments fell by 3.2 percent in the first quarter, in part due to the rise of tablets like the iPad. IDC said while the economy and lack of compelling new hardware experiences played a role, new tablets are also providing options for consumers. Apple is the clear winner in the early tablet race with 82 percent of tablet owners buying one, according to Nielsen, followed by the Samsung Galaxy Tab at 4 percent.

But it’s not just PCs that are being affected. E-readers and gaming machines are also getting used less because of tablets. Nielsen found that 27 percent of ereaders owner said they used those devices less since getting a tablet. And a quarter of portable gaming machine users and 20 percent of gaming console owners reported using them less or not at all since they got a tablet. Companies such as Nintendo are having to deal with the rise of gaming on mobile devices like smartphones and the iPad. Nintendo recently reported a 29 percent drop in revenue for its latest fiscal year as hardware sales dropped.

We’re still early in the tablet era and it’s not clear that all of these usage declines for other machines is solely due to tablets. Smartphones have also been easing our reliance on traditional machines. And there are external factors like a lingering tough economy that can affect some hardware sales. But the tablets are proving to be a significant presence in the computing landscape and will continue to reorder our hardware needs as they grow in popularity.

More than 3 out of 4 tablet owners (77 percent) said they used their tablet for things they used to turn to a desktop or laptop for. Some of the top reasons for using a tablet include is that it’s easy to carry (31 percent), has an easy interface (21 percent) and starts-up quickly (15 percent).（source:gigaom）
