    • Steve Jobs is the ultimate visionary. He has a vision, he implements it, and the world pays him tens of billions of dollars for it. He doesn’t ask customers what they want because they would ask for a faster horse, not a car. He knows what customers want before the customers do. He is the quintessent entrepreneur — the ideal that every founder strives to become.
    • Steve Jobs: “Originally, we weren’t exactly sure how to market the Touch. Was it an iPhone without the phone? Was it a pocket computer? What happened was, what customers told us was, they started to see it as a game machine. Because a lot of the games were free on the store. Customers started to tell us, “You don’t know what you’ve got here — it’s a great game machine, with the multitouch screen, the accelerometer, and so on.”

      “We started to market it that way, and it just took off. And now what we really see is it’s the lowest-cost way to the App Store, and that’s the big draw. So what we were focused on is just reducing the price to $199. We don’t need to add new stuff — we need to get the price down where everyone can afford it.”

    • Apple has changed the positioning of the iPod Touch twice. First, it was a multitouch iPod. Then it was a “game machine”. Now it’s the “lowest-cost way to the App Store.”
    • In this step, you use a combination of surveys and interviews to talk to your customers and ask questions like “In your opinion, what is the best reason for using our product?” If they say the best reason is playing games, start testing that positioning with new customers and see if it performs better than your current positioning.

    • 大旗网有着自己盈利模式———口碑咨询管理服务。王定标称:“们研究发现,在所有bb s和博客讨论当中,有接近20%话题是跟品牌有关。人们会有意识和无意识提到某一品牌,并给予评价。而被提及品牌公司则会对这些网络评价关心,这就成为口碑咨询管理市场需求。这些公司需要了解市场对产品看法,或与其产品之间比较性分析,或阶段性广告与促销状况,以此来指导修正下一阶段工作。”

    • Long polling is a variation of the traditional polling technique and allows to emulate information push from a server to a client. With long polling, the client requests information from the server in a similar way to a normal poll. However, if the server does not have any information available for the client, instead of sending an empty response, the server holds the request and waits for some information to be available. Once the information becomes available (or after a suitable timeout), a complete response is sent to the client. The client will normally then immediately re-request information from the server, so that the server will almost always have an available waiting request that it can use to deliver data in response to an event.

      Long polling is itself not a push technology, but can be used under circumstances where a real push is not possible.

    • Real-time services – Tornado supports large numbers of concurrent connections. It is easy to write real-time services via long polling or HTTP streaming with Tornado. Every active user of FriendFeed maintains an open connection to FriendFeed’s servers.

    • It is disappointing that Engadget can’t take 5 minutes and dig into this better.

      The MSM7201 is the chipset on the Android reference platform, so it makes sense that everyone’s first Android phone would use that chipset. To use a different chipset than the reference platform for the first phone would be foolish. After they get comfortable with the OS you will see chipset variation.

      In addition most chipsets weren’t Android capable yet. Google made the decision (correctly) to support one chipset originally and focus on maturing Android.

      You will see more variation on the chipsets under the hood very soon, as manufacturers get to their second and third Android handsets.

    • 由于美国电视节目的黄金时间在晚上7时左右,而此时很多美国人可能不在家,索尼的这款录像机为此大行其道,不过,就在视音频设备制造商日本胜利公司JVC开发出VHS制式录像机的一年之后,后者很快就超越了索尼的Beta制式录像机,控制了整个美国市场。

        原因是什么?

    • 索尼的Beta制式录像机实现的是一小时录制,而JVC的VHS制式录像机实现的是两小时录制。
    •   在市场已经有产品、并且该产品已经占据绝大多数市场份额的情况下,消费者一般不太会去使用另一种制式,但是很有意思的是,有一帮人也就是后来的“电影带租赁商”想到了“用户可以以很便宜价格进行录影带租赁的商业模式”。也为此,VHS制式录像机开始在数以千计的小店内大行其道。

        最后导致的情况是,当消费者去大店内,同时都有两种制式的产品在出售,而小店内却只有VHS制式。于是,依靠更强的网络效应,VHS很快就独霸了市场。

    • 但是,这并不是8848失败的真正原因。王峻涛说,这些困难后来很多企业都克服了,像阿里巴巴、当当、卓越,而8848却失败了。

      “今天来看8848失败的原因其实很简单,也很明确。”王峻涛说,原因只有一个那就是投资人对8848的核心业务没有坚持下去,他们去做别的了。
