With the Travelwide in mind I'm a bit gun shy to support another Kickstarter. Prototypes exist! Great! But remember, 'hardware is hard' and you can bet there WILL BE major delays. These delays would not be necessarily bad in themselves if, and this is a very very big if, the creators keep the backers informed, not just the good news but bad news too. I think backers get very tired of this "oh geez, sorry you haven't heard from us in the last three months but......"
How about this, if you are going to ask for money then you are required to make available to backers your personal contact info, including home address. If, after a long silence a project creator had to actually stand, toe to toe with a backer, whose e-mail questions had been ignored, then they might realize that after you take the money, you have some serious responsibilities. So unless you are prepared for those responsibilities, Don't. Take. The Money!
