Go Mobile:
Advanced laptop support so you get as much work done on the road as you would in the office, in addition to remote access to all of the data and applications on your office computer.The popularity of laptops shows that people are eager to use mobile technology. But the systems in use today are not as reliable and easy to use as many workers prefer. Windows XP Professional is designed to make mobile computing easier. This operating system is built to provide access to your information while you're on the go. The mobile computing improvements in Windows XP Professional build on the flexibility of Windows 2000 Professional. New features for mobile computing will help you accomplish as much on the road or at home as you do in the office, so you can be productive no matter where you are. Add these capabilities to the rock-solid reliability, performance, and communication features in Windows XP Professional--you have a system that can do things that you always thought a system should do. Access your office computer from anywhere: When you're away from the office and need a file or application that only exists on your office computer's hard disk, there should be an easy way to get it. With the Remote Desktop feature in Windows XP Professional, you can connect to your office computer from anywhere. You control your office PC while using your home computer, your laptop, or any other computer running Windows 95 or later. While connected, you can use most of your business applications, documents, and network resources on your office computer. Performance is excellent because there is no need to transfer files and applications over the network. Remote Desktop transfers only the screen data, keyboard input, and mouse clicks over your network connection.

Windows XP Professional answers that wish, with the new Help and Support Center.
