Price is everything. The EPIA's are a bit pricey themselves...its a good market though, not only are they lower in CPU horsepower, and less costly to ship, and less costly to make in terms of lack of expansion options...
but people pay a premium for them. People will doubly pay a premium for a PowerPC design, well for some people that is a detractor, but for those of us in this market, its not.
BUT, BUT, it still has to be within reason.
You all can decide for yourselves, but I say it has to be less than $300 U.S. or it will be priced out of the hobbyist market and into the hardcore-amiga-fan-only-maybe-there-are-2000-at-most market.
:-D
