I recently purchased a MacBook and I'm slowly getting acclimated to its 13.3" widescreen. My old (PC) laptop had a 15.4" screen with monster resolution, so I had no problem with screen real estate. While I am getting used to the smaller screen and resolution, I am really looking forward to trying out Spaces, one of the new additions to Apple's upcoming release of OS X Leopard.

In the meantime, Adam turned me on to a great Mac app that functions very similarly to Spaces. It's called VirtueDesktops, and it has greatly helped me in getting used to the MacBook's smaller screen. While it does have a few bugs (you can turn on motion sensor switching to take advantage of the internal sensor on MacBooks and MacBook Pros, but a too-hard tap on the keyboard or a coworker banging on the desk will cause your active desktop to switch; more than a little annoying) it will definitely fill the void until I can get my hands on Spaces. The main drawback that I've encountered with VirtueDesktops is that, while you can move an application window from one desktop to another, it's way too much work whereas Spaces allows you to drag and drop application windows between virtual desktops. But, this will definitely keep me in business until Leopard is released.
