Those hoping to use Robin's thoughtful cloud backup powers on Sprint or Verizon are no strangers to disappointment. After all, the startup announced its plans to build the CDMA model last September -- then a backer update issued this past January revealed the team had pushed back the device's launch from February to March, and then April. While it probably won't lessen the disappointment rippling through Nextbit's fanbase, Moss was surprisingly candid about why things went south. In short, it was just as much due to zeal to please everyone (he admits the team was "too optimistic, too bullish") to shoddy legwork from the carriers they tried to work with.

"What people at the carriers, in good faith given our need for quick answers, thought would take 'weeks' has turned into 'months,'," Moss wrote. "What they thought would cost 'hundreds of thousands of dollars' has turned into 'millions.' And we're still not there." Sadly, it's not clear if Nextbit ever will be -- here's hoping the team dusts itself off and does a better job managing expectations next time.
