I hear what you're saying, but again I fail to see what Amigas would have to offer, even if you did target the niche markets.
Looking at embedded systems and kiosks, people are not after a user level OS. What is needed there is a developer friendly OS that gives a high level of stability. In all honesty I fail to see how AmigaOS or MorphOS would be more suitable than an embedded customised Linux solution. At the end of the day users of kiosks etc don't care what OS the system is running on, only that it does what it says on the tin and does it reliably.
Being small might be an advantage if you're forward looking and carry no baggage, but that's not the Amiga scene. The Amiga scene is backward looking and carrying tons of baggage, and Amiga users are some of the most conservative in existence as this thread goes some way to prove. They don't want new and revolutionary. They want to return to what they had ten years ago or more.
Look what's on offer: a couple of pretty low-tech systems backed up with a couple of distinctly immature and non-descript operating systems, none of which offers anything unique or compelling. Buying in costs an arm and a leg, and requires that the user not be too demanding in his requirements (a modern browser or office suite being a bit too much to ask for, not to mention a practically non-existent networking infrastructure).
Except for the fanatical Amigan and the gadget meister, who'd want one and why?
