Don't mean to be a downer, but literally no piece of equipment I've crowd-sourced has ever shown up in my possession. I'd wait till they actually bring it to market.
The only thing I've crowd-funded was a "cloud" router, which I did end up with. But it was from a company that already had products on the market. It's an excellent router--I just bought a second one as a backup, because my job depends on being able to access the internet. The original is still going strong after three years, though. But the "cloud" function wasn't really ready for prime time on it (and there are too many other options for cloud storage now that are simply easer), so I picked up my backup on a discontinued items sale.
I'd cloud fund again, but not with expensive items. Router for $30? Yeah. $700 ebook reader. Ah, no...no matter how seductive that 13 inch screen is.
