The Raspberry Pi computers are extremely popular. It isn't hard to see why people like them -- they are small, inexpensive, and very useful for various projects. While they are arguably under-powered for use as, say, a full-time workstation, the diminutive machines aren't really meant for that.
If you do want to use it as a workstation, however, I have good news. Fedora 25 Beta Workstation is now available for both the Raspberry Pi 2 and Raspberry Pi 3. In addition to the Workstation image, Fedora 25 Beta Server is available too. Owners of ARMv6-powered Pi models, such as the Pi Zero, are out of luck, as the operating system will not be made available for them.
