Debian "unstable" is always quite up to date. All new features and packages are introduced in unstable first. Don't let the name confuse you -- it's about as reliable as most distributions' released versions. It's "unstable" in the sense that it gets constant updates, which means that things are always changing. Every once in a blue moon, a change will actually seriously break something for a day or so. Maybe once every 3-4 years in my experience.
I think that is painting a bit too pretty a picture of it. It definitely breaks more often than that. Count on having problems whenever the build system or the core set of libraries are updated, or whenever a larger set of software packages are updated like KDE. In these cases you seriously need to know what you are doing or you will end up in a situation where your packages get caught it a dependency deadlock. Your old packages have been uninstalled and the new ones won't install because of some missing package.
This happens often enough in my experience for me to not recommend running unstable unless you know what you are doing and are prepared to look under the hood when the emergency eventually arises, because it will.
