People should identify Kickstarter projects out of interest, enjoyment, or just a sense of fun, and contribute no more money than they would be willing to use as kindling to start a campfire. If you contribute $25 in hopes of seeing an indie film completed - great if it does, sad if it doesn't. If you contribute $100 hoping to get a new piece of hardware, don't expect anything other than some p% chance that you will ever receive that hardware or if you do it will work as dreamed. If you don't have the money to lose, don't contribute.
One innovative and clearly risky hardware project I backed has people complaining that the base product shipped 2 months later than planned (hoped) and the premium product will be 5 months late. Um, guys: it was risky. There were commercial alternatives available at 10x the price. You knew that this was an attempt to create a mini-breakthrough, but you're griping because it was 2 months late and the associated app will need some point revisions? Get real.
