Perhaps some companies are hesitant because they believe they would be pouring good money into a black hole. Or that the new attention derived would come in the form of mockery by ignorant spec-freaks so prevalent in the more mainstream platforms. See OSNews for a taster.
I think marketing in general is sensible, but initially aimed at those familiar with RISC OS, before trying to reel in some wealthy computing hobbyists with an aptness for trying out alternative platforms. By the way, I've repeatedly found people who've switched to the Mac platform are often very fond of features thought to be unique to OS X, but in fact were pioneered or are better implemented on RISC OS. Perhaps that can be utilised to gain fresh meat, ironically using the same techniques Apple themselves employ to attract Windows users. See their Get-A-Mac campaign.
"I also think it is about time ROL set out in writing (on their website) where they see RISC OS development going in the next 5 years. A sort of roadmap."
Yes, which seems more reasonable now that the Great Work of 32 bitting and abstracting away legacy innards is (almost) completed. In the past ROL has commented that they develop all sorts of stuff and when a Select release is due (...) they look at what new features can be finished for inclusion.
"Warming over some documentation is all very nice, but what the Select scheme needs is actual releases of the operating system with new features, and not gaps od 3 years. Until they have proved they can achieve this, it would be very unwise to recommend throwing more money at them."
Indeed, but believing what ROL is saying for a moment, these gaps should be done with now. RISC OS has been thoroughly renovated and is now ready to grow again, with hopefully the kind of regular feature updates as seen in the past. However, I suspect they've lost a lot of subscribers during these silent periods, mostly due to their own failings to communicate properly. The dilemma now is that ROL may have great difficulty in proving that the Select scheme is viable again.
"Iyonix users are fully aware of what Select could offer, if ROL had any intention of supporting them."
I'm not entirely sure of that first part, but it's essential ROL start making actual commitments to Iyonix users. If that would result in the same BS we've seen before (the infamous 100 user pledge), they deserve whatever is coming at them.
