I really want to like the AM1 platform as well, but as far as meeting usage needs, I find that it is surprisingly squeezed between the intel platforms you mentioned and the vastly cheaper/lower wattage raspberry pi 2 (and now 3) systems....or even the Pine 64.
If you're just web browsing, emailing, etc, the pi is adequate. If you need more performance than that, it's likely you need a lot more performance and the AM1 sits in a middle ground there isn't much demand for. It does make a good minimal HTPC for 4K video if you want to run windows on your HTPC, but that's all I can think of. (the just released Pine 64 board supports 4K video playback for much cheaper, but only runs android).
