At the end of the day, like I said a year+ ago - a X1000 will not do a thing different from a lowly SAM 440. Will it run Blender quicker? Sure. OS4 machines are fun little machines to putz around on, and until there's some sort of more varied software for them they will be not much more than a novelty. You cannot even type up and save a native Office format grocery list on this $3000 machine, just like I can't on my SAM. Even the $25 Raspberry Pi should be able to do that when it's released under Linux.
We need modern software for these machines something terrible.
So will the $150 PC in the corner, in fact the PC will run circles around the X1000. If you bought a high end NG Amiga machine for serious rendering purposes, it may be enjoyable working with the machine, but your productivity is suffering.
I hope those who bought them enjoy them and bought them for the right reasons and love them for what they are - fun hobby systems. I certainly overpaid for my SAM, but I do enjoy it and I am not silly enough to try and justify the $1000 I spent on it in comparison to what it can do compared to modern machines. Truth be told, my iPad is more useful for modern computing and consumption.
Regarding gaming - I'm about to do something I've never done, and that's agree with Takemehomegrandma, as well as Agami. The Amiga will never be a contender in gaming again, not in a market of $500 3ghz cheapo PC builds that can run BF2 and games like Skyrim. Gaming, as Agami said is also becoming quite platform redundant with things like the iPad as well. Never thought I would see the day where I could buy GTA 3 for my Ipad (for $5), and it's every bit as good as the original was and I can play it anywhere.
