"Why? Simply put, it keeps things easy to manage. I am able to use a LTS release on any of my daily use boxes while still being free to take the latest Ubuntu releases for a test drive should I wish to from a LiveCD.
"So despite Ubuntu being deemed as "too bleeding edge" by some, Ubuntu has proven to be a practical choice for myself personally.
There is also another reason I rely so heavily on Ubuntu. It's where the bulk of the community support is. Add this to the fact that my PCs will run perfectly with the peripherals of my choosing -- and that having to configure anything out of the ordinary is highly unlikely -- and Ubuntu becomes the path of least resistance when opting for a Linux lifestyle."
