As of a few minutes ago there were 3,696 'backers, accounting for a total of 14,279 Digispark units. Apparently the Ayn Rand engineers missed the point on this thing.
First, I suspect that not many people ever left their arduino 'in' something, and, like test gear, it's their property to do with as they please. The naysayers might think of that. Oh, and look up the definition of irony. Or, if the video was hiding it in plain sight, sarcasm.
I know that many of the technically competent posters are fully conversant with Dip-Trace, Gerbers, G-code, solder mask, Altium, Haas CNC, have established relationships with board houses who never foul up their boards, can design and produce their own PCBs in under five minutes at home, have a full range of carbide drills and the appropriate drill-press. Apparently many of the technically competent can program in 27 different languages, troubleshoot circuits from the simplest relaxation oscillator to systems that have hot-end extruders run by IBM 370 'frames, communicating over a combination of Xbee and 300 baud modems (yes, the acoustically coupled ones in the wooden boxes, dial phone) and never worry about a lack of skills, parts, knowledge.
Some of us however (this is me, particularly) want something I can afford to blow up, throw out, give away, not fully understand, curse, and delight in.
If having fun makes me an idiot, well, I'm a drooling idiot.
Maybe you could think about the possibility of adding to the Arduino environment - oh, no, it's a ghetto - rather than bad-mouthing not only the guy who presents the product, the now 3,700 backers. That's right, while you're whining, thousands of people see possibilities.
Now, back to having some fun. Where did I put that Taser?
