This. I've been following this product since it was first announced and I know it's been a looooooong road to travel for the team. If anyone is pondering doing a similar hardware product, you should check out the UHK blog because Laci goes into a lot of technical detail about development, procurement, and certification issues the UHK team ran into over two years.
I was mad when the projected date was missed, but as time went on, I strangely got less mad until I just threw up my hands and said "It'll be here when it's ready." I'm glad they didn't cut any obvious corners trying to get this out to meet angry customers mad about the ship date.
