Conclusion: The InFocus X3 is light enough to be relatively portable but big enough that you probably won't want to carry it on many business trips. It throws a reasonably bright image, offers excellent contrast ratio, and is inexpensive enough to count as a good value.
Pros: Reasonably bright image. Excellent contrast ratio. Good image quality. Audio volume is adequate for a small room. Straightforward menus.
Cons: Composite video images (but not S-Video) are a little washed out.
