LOLI'm not saying it's expensive nor complicated, I'm just saying it's a pure investment in BTC: you can't do anything else with it. No playing, no reselling, just mining.

True, how ever for $149 I know a lot of guys that would take a crack at buying one and figuring out if they could mod it or if it really has just one use. There are very talented "engineers" out there that can reverse engineer the tech and use it for something else.
