EXPLANATION

Windows 7

This feature is built in, and it's called Aero Snap. You can use the following keyboard shortcuts to get the behavior you want:

• Win + ← moves the current window to the left half of the screen.
• Win + → moves the current window to the right half of the screen.
• Win + ↑ maximes the current window.

Windows XP and Vista

GridMove allows you to setup regions to snap windows to via a shortcut key. I mapped Win + 1 to move a window to the left half of the screen and Win + 2 to use the right half.
AeroSnap makes Windows 7's native keyboard shortcuts available in Windows Vista and Windows XP.

Mac OS X

Cinch, SizeUp (both unlimited free trials) and TwoUp (discontinued – available here) from Irradiated Software all accomplish this task perfectly. SizeUp adds some extra features, including multiple monitor support.
