1: The route taken by Castle was dictated by ROL's stance at the time that they were not prepared to 32bit RO, together with previous experience working WITH ROL (kinetic) which indicated a likely timescale totally unsuited to bringing a product to market. (Iyonix was approx 8 months from conception to launch!)
2: Castle made a business decision to BUY RISC OS when it was offered for sale, at a not insignificant price.
3: In deference to the licence that ROL do have (from Castle, the current RO Owners), Castle did not encroach on the ROL market for 26 bit machine OS, which is why RO5 is only on the IYONIX. STD had the opportunity to approach Castle for a 32bit version of RO, but for their own good reasons chose to go the way they did.
4: Cornering market: Competition in hardware is generally healthy. Please do not assume your (I presume) motives are Castle's
p.s rose tinted spectacles are not generally compatible with investment.
