What would you recommend they do to increase the user base?
As far as I can see both the low end (Sam 460) and high end (X1000) are covered. Criticism over the price is noted, but the price level is mostly out of Aeon's control. If you don't want to pay that much, buy a Sam. Criticism of the price as the only factor is equivalent to an old school Amigan wondering why they can't buy an A4000 for the price of an A600.
No, it would rather be: why does the A600 costs the price of a 386, the 386 being the equivalent of the A4000 ?
