Never to late to become an Amigan. An Ars Technica tech writer without any prior Amiga experience reviewed AmigaOS 4.0 as well as recently AmigaOS 4.1.
His conclusion:
AmigaOS 4.0
"The release of AmigaOS 4 proves one thing: you can't keep a good platform down."
"I can see why its diehard fans have held on to the OS despite having to wait so long for a new version to be released. Call me crazy, but I'm an Amigan now, and will be as long as I can. This OS has struggled past incredible obstacles—both financial and psychological—just to exist, but I'm already anxiously awaiting its successor. "
AmigaOS 4.1:
"Whatever the ultimate fate of AmigaOS, it has been a privilege and a joy to use it. I still use my AmigaOne on a daily basis, and consider it my "fun computer." Whenever Windows or OS X annoys me, it's right there, fast and friendly and accessible. It feels like a personal computer in ways that computers haven't felt like in over a decade. "
