评测:作为网络广播工作站的惠普Z1
HP's Z1 is the first all-in-one computer with workstation components and field serviceability. 在这里, encoding expert 1月时 takes a look at how this workstation-class portable PC fared in a live production and webcast environment, 测试重点在3个方面:渲染, 流媒体编码, 实时编码.
This is the unofficial third segment in a multiple-part series on webcasting JStreet.org [http://jstreet.的全国大会. 在本节中, I'll focus on the computer I used to webcast the conference, 惠普的新Z1工作站, 所示 图1(下面). 计算机是如此的新，以至于在会议的时候, it was still not formally released (its official release date is April 16), perhaps making the JStreet webcast the first time the Z1 was actually used in a production event.

我想把Z1停在乔治城的酒吧里, 就像著名的iPhone原型一样, but it's a bit too big to carry around and well past the prototype phase. 除了, 在和Z1一起工作了几周之后, 你最不想做的就是把它放在任何地方. 但我有点超前了.
美女的诞生
The Z1 is HP's first all-in-one workstation with a huge 27" display that dwarfs the 17" notebook you can see on its right in 图1. 为什么是一体化工作站? Primarily for the size; HP saw a need for a workstation-class product that could fit into the shrinking spaces inhabited by the creative, 设计, and financial executives who buy a good share of HP's traditional workstations.
显著, the Z1 is the first all-in-one computer with workstation components and field serviceability. 比如传说中的Z200, Z400, Z600, Z800工作站, you can open the case and change most components without any tools (下面的图2). According to the HP officials who briefed me on the product, 现场服务能力是一个关键的产品要求, since their professional customers didn't want a product they would have to return to swap out a failed optical drive, 电力供应, 或者显卡.
