Well, I can only speak for myself.
And when I read that a new Comodore incarnation would want to take the Amiga platform to a new level I felt a mix of unbelieving amazement and pleasant anticipation initially. But this was replaced by disappointment when I read that their new hardware would be a bog standard x86-PC mobo in a re-created all-in-one classic case, meant to run an Amiga-like skinned Linux derivate - mostly for gaming purposes (WHD load) - which would presumably not be able to run native 68k apps.
As I'm not interested in gaming, but in CAE/CAD/CAM/robotics/CNC and all sort of engineering tools in general, I lost all initial hope of ever being able to run my old 68k Amiga apps covering these fields (which are still fully usable in 2011, b.t.w.) on their new systems.
Furthermore I moved from my trusty, old A500 to the A4kPPC in a BigTower because of the better expandibility as soon as I could afford it. Although I had expanded the A500 to the limit I had need for more expandability.
As I doubted that any of C=USAs new devices could offer me this expandability, I realised that I don't belong to their target group.
Basically I don't mind the idea to run the Amiga OS on x86 systems because of their prices and availability, as long as that means I can still use my old native 68k CAE/CAD/CAM/robotics/CNC-apps and all my old 68k engineering tools, which have cost a fortune back in the day (e.g. 2.500 DM just for DynaCADD).
As I would need those apps only for hobby purpose today (e.g. to design and build an steam operated H0 scale steam locomotive that can be remote controlled from the Miggy on a model railway), I don't like the idea of having to spend a fortune again on buying Linux equivalents for all the engineering tools I already have on 68k. Even without that I still would have to spend enough cash on the required CNC machines, when it comes to the realisation of the project.
I don't know why you would think that. CUSA's machines will certainly be able to run 68k code. They will do it the same way that any of the PPC Amiga solutions would run it, via emulation. PPC processors do not run 68k code natively any more than an x86. CUSA has stated that they have the rights to distribute the original Kickstarts and Workbenches, and that they will be integrating UAE into their distribution. This means that all of your existing 68k applications should work just as well on a CUSA system as on an OS4 or MorphOS system.
