I have followed this discussion with interest, and have come to the following conclusions:
1. ARM-based hardware is increasingly outclassed for desktop use; 2. Emulation under Windows means the death, sooner or later, of the platform as a live entity; 3. Development of new native hardware is expensive and risky compared to 'software' solutions, and is therefore increasingly less likely to happen. In fact, we may be in a vicious circle where lack of support leads to less motivation to develop new hardware leading to further loss of support and so on. So Julian Zimmerle's proposal, if technically feasible (and I am not qualified to judge), seems the most attractive option to me. But who is going to do it?
A final point: the RO GUI still has a great deal to recommend it IMO. I have been using Windows XP for the last 3 months and, if you have to use Windows, it's the best yet. But it doesn't come close to RO for intuitiveness and ease of use; it's still essentially what it always was, a cumbersome, business-orientated, 'linear' system. If RO could get to run on genuinely fast hardware it might start regaining support on its own unique merits.
