第一台基于键盘的掌上电脑问世时,曾引起了IT界极大的轰动,不过,它并不是面向一般计算机用户设计的。由于键盘和屏幕过小,与其它计算设备沟通困难,迫使大多数经常需要外出的人更愿意选择更重但功能更强的轻型手提电脑。 然而,掌上电脑的设计已经发生改变。更好的键盘、屏幕、Modem和软件使得今天的基于键盘的掌上电脑更便于使用。 When the first keyboard-based PDA came out, it caused a great stir in the IT world, but it was not designed for general computer users. The difficulty of communicating with other computing devices as the keyboard and screen are too small, forcing most people who often need to go out to prefer lighter but more powerful laptops. However, the design of the handheld has changed. Better keyboards, screens, Modem and software make today’s keyboard-based PDA even more user-friendly.
