The problem is that there are so many s/ware and hardware areas requiring development it is unrealistic to expect a company with Castle's level of financial clout to develop all of them. Does Castle have a higher t/o than Acorn? I doubt it, yet the effort of maintaining RO as a fully up-to-date OS in all areas was beyond Acorn in 1998, and they abandoned it: needless to say, OS requirements have become an order of magnitude greater in the last 6 years.
The only solution is to determine which areas are key, and concentrate developmnet effort on those. Education may or may not be one of them: it's a truism of commerce that it's easier to keep existing business than to generate new business, but probably it's too late now. However, Jack Lillingston has not survived this long in a tough market by not being a clear-thinking and shrewd operator, so hopefully there is a plan. The main thing is not to spread limited resources too thinly.
