On my work machine (laptop) I've been on Debian sid (unstable) for a few years now, which is probably close to what they have in mind. For somewhat experienced users this works great: Occasionally there are a few hiccups, but they are few and usually easy to fix or work around. But I would not recommend this to inexperienced users, and I think there the current Ubuntu rapid release cycle hits a sweet spot: It's reasonably well tested to be able to recommend it to inexperienced users or set someone (grandparents, ...) up with an Ubuntu box and just let them have a go at it, while also being mostly up to date.
