It was an impressive hardware design more than 10 years ago, but certainly not today and especially not with a $3,000 price tag. Unlike the original Amiga, the X1000 has neither a hardware or price advantage. Its only real selling point is that it is able to run Amiga OS4, which is only an advantage when selling to die-hard Amiga fans as even Linux can do more than it. And why buy an X1000 to use Linux when you can by a more powerful PC for less than 1/3 the price of an X1000?
Linux can always do more on any hardware, that is a rule with few exceptions these days, but it doesn't prevent me from enjoying other operating systems as well.
My subjective comment regarding X1000's impressive hardware design was specifically within the PowerPC architecture. The idea of bringing the XMOS chipset into the mix (Xena), that Xorro port with all those GPIO pins just waiting for new hardware project ideas which runs independently from the CPU (I'm drooling just thinking about it). I never claimed that X1000 outperforms current PC hardware. Also, having used Linux on PowerPC in the past I can tell you that there is special kind of feeling you get compared to any kind of x86/x64 based architecture, it's just smooth and without lag even when the system is under load. I haven't tried AmigaOS 4.x on X1000 specifically, but considering it's less bloated than Linux I assume it is really fast.
Thinking of performance, even my A1200 boots WB 3.1 faster than any modern OS on the latest PC tech, it even boots faster than my phone, so in that aspect it outperforms everything else.
Your argument is like telling someone who paid $30,000 for a Harley Davidson that he should have bout at $15,000 Kia because the Car has 4 wheels and airbags. You're missing the point that the guy wanted a motorbike. 
I agree.
