While it would require me setting up a blog, it would probably be worth it.

It could almost be a business venture, given the fact that an off the shelf media product is upwards of $100 here in aus, if you could create a decent linux media center experience for the device, and a nice case, you could flog it for waves hand about $80 per unit and be ahead (provided the mark-up took into consideration all your costs).

Would fly in the face of the educational/not-for-profit Raspberry Inc though.

I'll find somewhere to write about it though.
