"Mouse Across Borders" is a Microsoft utility which "links" multiple (up to 4) monitors together to use a single keyboard & mouse across them all. Might be useful for some folks here who program on one screen, manage data on another, and display output on another. Haven't tried for myself yet, just heard about it.

Utility also lets multiple users share screens & data seamlessly. Cool beans!
