An Amazon exec revealed last year that the company's continuing to develop more Fire phones despite the first one's failure to sell. According to The Wall Street Journal, though, that might not happen anytime soon: Amazon's shelving future phone plans, among other projects, and has even laid off a number of engineers from its secret Silicon Valley hardware development center, Lab126. That's the same facility responsible for the Fire tablets, TV and phone, the Dash button and the well-reviewed Echo speaker/voice-activated assistant. Lab126 was formed back in 2007 -- named as such to represent the first (A) and the 26th (Z) letters in the alphabet and, hence, the company's logo -- to develop Kindle e-readers. Unfortunately, the Fire phone's failure to sell (which led to a $170 million loss) forced the company to merge, stop or scale back many of the its (rather interesting) projects, in addition to cutting jobs.
