Ars reviews the Amiga X5000, and concludes:
The X5000 is different. It feels like an exotic car: expensive, beautifully engineered, and unique. If you bought one, you’d be one of a proud few, a collector and enthusiast. It practically begs for you to dig in and tinker with the internals – the system comes with an SDK, a C compiler, Python, and a huge amount of documentation for things like MUI, the innovative GUI library. On top of that, there is the mysterious XMOS chip, crying out for someone to create software that leverages its strengths. It feels like a developer’s machine.
Should you buy one? That depends very much on what your needs are. If you are simply after the best price-to-performance ratio for a desktop computer, this is not the machine for you. But if you are interested in something very different, something that is pleasant and fun to use, and yet can still be used for modern desktop workloads, then the X5000 is worth a look. I have had this review unit on my desktop for over a month now, and frankly I don’t want to give it back.
I reviewed the sam440ep with AmigaOS 4 way back in 2009, and came to a relatively similar conclusion – these machines are a ton of fun, but they’re just prohibitively expensive, meaning only existing AmigaOS users will really get their hands on these. They really, really need a more accessible machine or board – a few hundred Euros, tops.
