A friend of mine is looking at buying an office and workspace, to do his milling/lathing/dirty stuff......just stops working the moment your connection fails. Even in the best of countries when it comes to broadband penetration.
I'd still think it's a small percentage - I'd be generous if I said it's 1% for the US. No? And I can't imagine running any kind of company in this day-and-age, without internet. That would be impossible. A machine shop, like you said, might just be one of the few that could.
With that said, I think it sucks that whole countries might be left in the dark for using CM, but it's not the only game in town right? Such is life. (I really believe internet should now be a basic human right - just as much as freedom of the press once was - so don't get me wrong - but that's another topic for another day - so you can put that away)
There's going to be a vocal minority with bad internet connections that will hate it. But that's a small percentage of people. They have to make it an online only tool, and force the project files to the public so that it won't eat into AD sales.
Nope, they just have to set sensible limits. Their problem here is that they gave practically everything away for free. That's both noble and completely stupid.
Dave, you're not thinking like a marketing guy! Duh! (CS - not worth mentioning - we would both agree that's dead in the water) The whole brilliant idea is that they destroy/interrupt/shake-up the 0$ market for low end, and position themselves as the OSHW and educational king. (I'm not saying that's what's good for everyone, I'm just looking at it as a business decision) - their cost to give away CM is nothing compared to the fanfare they will get. Again, looking at it as a smart business decision.
RE: "sensible limits" Yea, they could have made $50 here, or $100 there on upgrading to a 4 layer or "bigger-then-an-arduino-sheild"/eurocard layout. (for a company that is use to 10k-100k orders, $100 bucks is an annoying about of money to have to book keep) But here's the rub.....once you take people's money, they want support, and they will be forever emailing you why their software that "THEY PAID GOOD MONEY FOR" doesn't work. You give it away, start a forum, and all of the sudden people are happy to support the product on their own. You just saved yourself ($200k? At least!) a year in customer support personal.
Chris Anderson, in his book "Free: The Future of a Radical Price" is a great read, if you haven't already read it. The psychology of "free" is a powerful thing. I think if you get it on audio book, he personally he reads it(or I might be thinking of his other book). Give it 1-2 chapters in, it's very interesting.
Anyways, you video review of it(CM) was awesome(it'll be on HAD later today) - would love to see you do a start to finish capture-to-layout-to-gerbers of something simple like your uCurrent.
