Your snark reinforces my questions about using any of the current offerings whose price doesn't require mortgaging the house. And I have so many questions that go unanswered. For example, what's the print speed in terms of volume e.g. cubic millimeters per second? And I had to scoff/chuckle at CubeX who won't tell you exactly how much material is in one of their cartridges. When I asked, they said "Oh, you can print about 75 cellphone cases." WTF? A cellphone case is not a standardized unit of measure, doofus.
For me, the killer app is printing custom PCB enclosures. Makes you wonder why COTS embedded computer manufacturers don't have a meeting with companies like Hammond to make enclosures that fit (and skip the fancy styling because that stuff isn't going to sit on a shelf). But I digress. So I want to print enclosures but my concern is that they take a day to print and the print fails 8 hours in. My other concern is that they look like crap on the outside. People are buying home frying machines, filling them with acetone, and dunking their prints in hot acetone to smooth the layers. Beyond that, you have to wonder when Makerbot comes out with a failed print shredding machine so you can recycle the plastic into new filament.
