1.前言
也许对数码玩意的热爱是男人的本性，就像女人对化妆品的喜爱和看到了心目中的帅哥的感觉。从开始使用手机和笔记本之后，就喜欢上数码玩意。随着年龄渐长，在岁月车轮的碾压中和时间风车的吹拂下，各种各样的感情已经慢慢起着变化，甚至面目全非，但心中依然留着对数码玩意的那份喜爱之情。只是更多地多了理智和考量，少了些冲动和不顾后果。渐渐地，购买一个数码玩意来对自己的学习生活有所帮助，进行更加高效的自我时间管理的想法也提上了计时日程。我一直深信自我的，自发的前瞻性的，而不是靠外部的约束和压力的时间管理和安排才是最高效的(这好像也是哪本书里面说到的)。
由于一个偶然的锲机，在老婆大人的支持下，俺开始了寻觅智能手机的历程。感谢互联网和Google这样的伟大的应用。新的一扇窗口在我面前打开了。
1.1 第一个问题：是买个PDA + 手机（俗话说得双抢）还是买个 带手机功能的PDA, 或者买个带PDA功能的手机？
高速前进的现代科技和工业，还有不断细分的各种各样不同消费群，使得市场上充斥着丰富的产品。可供的选择是如此之多以至于让人眼花缭乱。
打开互联网：一大队眼花缭乱的名次：PDA, SmartPhone, PPC， windows mobile, Windows CE, Symain, Linux..
还是正本清源吧,先看看这些东西的定义：在Google上输入define: PDA, define: SmartPhone,
采用Wiki上面的定义吧：
PDA:
Personal digital assistants (PDAs or palmtops) are handheld devices that were originally designed as personal organizers, but became much more versatile over the years. A basic PDA usually includes a clock, date book, address book, task list, memo pad and a simple calculator. One major advantage of using PDAs is their ability to synchronize data with desktop, notebook and desknote computers
SmartPhone:
A smartphone is any electronic handheld device that integrates the functionality of a mobile phone, personal digital assistant or other information appliance. This is often achieved by adding telephone functions to an existing PDA or putting "smart" capabilities, such as PDA functions, into a mobile phone. A key feature of a smartphone is that additional applications can be installed on the device. The applications can be developed by the manufacturer of the handheld device, by the operator or by any other third-party software developer.
It is increasingly difficult to define exactly what qualifies as a smartphone. Nearly all phones have some rudimentary PDA functionality such as phonebooks, calendars, and task lists. Furthermore, BREW and J2ME devices allow for the installation of additional applications but are still not considered smartphones. There are many BREW devices with PDA functionality, the ability to run third-party applications in native code and sporting displays as large as 240x320 pixels; yet they are not considered smartphones. The elusive definition seems loosely tied to the particular operating systems listed below.
The first smartphone was called Simon designed by IBM in 1992 and shown as a concept product at COMDEX. It was released to the public in 1993 and sold by BellSouth. Besides a mobile phone, it also contained a calendar, address book, world clock, calculator, note pad, e-mail, and games. Customers could also use a stylus to write directly on its screen to create facsimiles and memos.
As of 2004 smartphones are an increasingly large part of the mobile phone market. According to analyst house Canalys smart phone shipments increased over 100% from 2004Q2 to 2005Q2, with over twelve million devices shipped in the latter period[1]. In a couple years, it is likely that most phones sold will be considered smart, except for disposable phones.
Most common operating systems are Symbian, Palm OS (developed by PalmSource), Windows Mobile (formerly known as Windows CE, and developed by Microsoft), BREW (technically a platform developed by Qualcomm), and Linux
