jms: "Castle could end up making STBs or embedded systems with no interest in the desktop market"
You need to listen more carefully to Castle presentations. That's not Castle's aim, and they certainly don't have the naive approach that Acorn had regarding big external customers hopefully descending on them with big chequebooks. Yes Castle *do* want to take advantage of investment from larger companies, but the reason they're putting huge efforts into the enthusiast market is that thousands of enthusiasts spending a thousand or two pounds each is still a very worthwhile amount of money - that's not going to change fast.
Do you know of any companies who got rich making set top boxes? I don't.
Watch this space for a more detailed examination of some of what Castle have been doing and saying recently - it may meet some of your concerns.
Incidentally, I've been a Select subscriber all along, I've bought an Iyonix and am considering buying a second Iyonix. I don't consider my Select subscription wasted, I could always keep a Risc PC and put RISC OS 4.39 on it for fun.
