I do video editing, 3D rendering, a few other resource intensive tasks, I like to think that I get all eight of the cores in my main machine a little warm...
But you are right, there's really not that much to do on AmigaOS, so the need for power isn't really there.
Compare 1985 and the '80s in general with today. Amigas were arguable at at about the same power level as PCs and Macs and were cheaper than Macs and name brand PCs. There was modern software available, and things like lightwave and video toaster which you couldn't do on a PC/Mac. When you bought an Amiga you bought state of the art. Part of the flakiness of AmigaOS was excusable because it was pushing the hardware and software beyond the breaking point and there were no guardrails.
Today the X1000 is a little better spec'ed than a netbook, there's no software available that I can't run faster or better on a Mac or PC. Price/Performance wise they make Apple Store look like Tescos... Nothing is state of the art, the world is talking eSata and USB 3.0, AmigaOS hasn't even nailed down USB 2.0 yet. XMOS? For USD 100 I can stick a USB board in a PC and have all the tools to actually make it work available to me. The X1000 does not in any way, shape or form represent the spirit of the original Amiga.
Certainly overpriced* (for now), but certainly not underpowered. Tell me Persia what exactly the average user uses their computer for these days and what do you use yours for?
*How exactly is a company with limited funds able to go on and make better things and re-invest without actually making a profit? Pray tell.
