3G时代,最诱人的就是高速上网,不过手机终端的利用率不高,上网资费的价格不低,在今天看来依旧是迈入3G时代的门槛。不久前,中国移动推出了G3上网本(注:G3为中国移动的3G网络品牌,3G则指第三代移动通信技术),通过补贴政策希望大家能够真正有效的利用到3G高速网络。之所以选择上网本,无疑,价格低(与中高端手机价格一致)、合理的补贴政策,似乎都是一个比较 相似文献

2009年,EPC的爆发彻底带火了整个上网本市场,它以其精致迷你的外形、低廉的价格,吸引了很大一部分爱美人士。抛开外观来说,其配置和性能还是没有完全赢得消费者的心,从而为那些看似质优价低的低端笔记本留存了一定的市场。然而,两者的产品的变化纷杂,时而有融合之势,时而又争锋相对.在消费者面前撒了一团迷雾令人琢磨不清,取舍两难。今天本刊小编就此将两款笔记本类型做一PK.不为一决高下,但求尽绵薄之力,帮广大消费者把把脉.理一理消费的思路。 相似文献

那些爱好使用上网本来进行创作或工作的人们,准备好来自众多厂商的围攻吧,半导体厂商,PC厂商,软件制造商,电信运营商。这就是我参加中国台北电脑展的最大心得。 相似文献

Cars offer an excellent example of ubiquitous computing, and a technological revolution is currently underway that will eventually see in-vehicle computers empowered with increasingly complex sections of the driving task. In this article, we critically review the effect of ubiquitous computing in cars with reference to the psychology of the driver and present a survey of automotive researchers drawn from five major carmakers. The results illustrate the role of the computer in vehicles over the short, medium, and long term. Systems that are likely to be fitted into vehicles in the next 5 years include sophisticated electronic architectures and greater penetration of navigation and telematics systems. In the next 5 to 15 years drive by wire and collision sensing are anticipated. In the long term, 15 years and beyond, advanced driver-assistance systems will increasingly automate the driving task, and in-car personal computers and Internet will be commonplace. We conclude that the increased complexity and prominence of computing in cars requires further investigation of the needs, abilities, and limitations of the driver if the aims of safety, efficiency, and enjoyment, as well as greater ubiquity, are to be realized. 相似文献
