Time is definitely huge. I've got one of the knock-off fidget cubes on my desk right now, a Christmas gift, but my kickstarter-backed one doesn't arrive until later today. I expect the real one to be higher quality, but it seriously got scooped.
Yeah, I supported the so-called NiftyDrive(a micro-sd adapter that fits within your SD card port in a macbook) because it was such a cool idea at a time - but they had several delays, and in that time, I could just get an identical adapter off ebay, delivered next day, for 1/3 of the price.
Also, supported the nifty drive... great idea, by the time I got it, I didn't need it anymore.
Today's mail arrived, and yes, as expected, the KS version is nicer (except for a few things).
