Hardware, Embedded Systems "In the past five years, flash memory has progressed from a promising accelerator, whose place in the data center was still uncertain, to an established enterprise component for storing performance-critical data. It's rise to prominence followed its proliferation in the consumer world and the volume economics that followed. With SSDs, flash arrived in a form optimized for compatibility - just replace a hard drive with an SSD for radically better performance. But the properties of the NAND flash memory used by SSDs differ significantly from those of the magnetic media in the hard drives they often displace. While SSDs have become more pervasive in a variety of uses, the industry has only just started to design storage systems that embrace the nuances of flash memory. As it escapes the confines of compatibility, significant improvements in performance, reliability, and cost are possible."

"All of these need to be gracefully taken care of and reinitialized, and if possible made to continue previously interrupted tasks. All of this is already handled by current OSes. And all of this is very, very messy and complicated."

Indeed, however it's complicated BECAUSE they use volatile ram. All of that mess could be avoided in the future with NV-RAM. That's the point, hypothetically if future NV-RAM could be built to be as practical as normal RAM, then there wouldn't be a reason to use normal ram anywhere. Making devices power up into their previous state would be free, or next to it, without any of today's complications caused by volatile ram.
