Amiga users are the longest-suffering technology loyalists that the computing industry has ever seen. Though once the best solution for 3D and special effects work, the operating system has long since been superseded as mainstream options, such as x86 hardware and new Mac and Windows operating systems, have become more powerful.
For instance, AmigaOS only gained support for memory paging in 2008, with AmigaOS 4.1, and USB 2.0 in 2011, with AmigaOS 4.1u3. That's over a decade after the USB standard was released, and three years after its successor, USB 3.0, was finalized. Amiga support for modern operating design and peripheral hardware is, to say the least, beyond hope.
On top of that, AmigaOS only supports dead, 32-bit processor architectures. AmigaOS 3.9 supports the Motorola 68k series up to the 68060 (released in 1994). AmigaOS 4, while slightly more modern, only runs on older P.A. Semi PA6T, Freescale e600, and IBM 750 parts. At best, AmigaOS is a decade behind.
So what is an Amiga user to do? If you're at all familiar with Unix or FreeBSD, there is one option out there that Amigans can look to—as long as they're okay with rock-hard stability, modern operating system design, and pervasive 64-bit support.
