The value of the Pi is, that it is affordable brand-new. You can buy one or as many as you want and be sure that they are in a perfect working state, no repairs or special set up required. Just having identically machines is of extreme high value, if you are looking not only for a personal item, but something you can rely on for some kind of professional work.
Another nice thing is, that the Pi can boot and work solely on a single micro-SD card. That makes it easy to have any number of install "disks" ready at hand, you don't have to set up the systems hard disk first.
Finally, the Pi gives you a nice set of IO-ports, you can immediately start with any hardware tinkering project.
