Yes, but find me a laptop that runs RISC OS natively. Granted you could go down the Virtual Acorn route, but there are those users that want to do everything the hard way. Jess did say it would be a niche market, after all.
I think the hardware is probably more interesting as a small, discrete, low-power server, possibly handling gateway, print or media services. However for all those tasks, I would tend to think BSD, Linux, or Windows before RISC OS. Plus I don't actually know how the A9home compares in size to a mini-ITX based system. And also, for media tasks, the A9home doesn't have a TV out unlike those mini-ITX boards.
