I don't use Ubuntu because I'm cheap, I use it because it's the best tool for the job. I think in general Ubuntu users are going to be developers(read have expendable income to spend on gadgets). I think making a play for the high end is the smart move, create a device everyone wants and aspires to own and they will sell themselves. Also if your main market is developers(as I'm assuming it is for the Edge) then you need to blow them away with a beautifully designed high end device to get them to buy it and then start developing the app ecosystem.
