If you were deploying Ubuntu company-wide and had custom desktop software, you'd want an LTS release on the desktop too, for the same reason.
Stability versus agility is a trade-off. In some cases it makes sense to pick a fast-moving platform. In others it makes sense to pick a slow-moving one. With the combination of a six-monthly release cycle and three year support on LTS releases, Ubuntu gives you both platforms to pick from.
"This is where Ubuntu Backports comes in. The Backports team believes that the best update policy is a mix of Ubuntu's security-only policy AND providing new versions of some programs. Candidates for version updates are primarily desktop applications, such as your web browser, word processor, IRC client, or IM client. These programs can be updated without replacing a large part of the operating system that would affect stability of the whole system."
