While there may be plenty of gotchas to worry about, and a long time between now and a reliable implementation, I think you may be a little too quick to dismiss it. In (perhaps only?) my imagination, it may in fact, be so much better at (say) caching functionality, or versatile at dealing with (or redefining) ordering, that new paradigms may pop out of it -- who can forsee?
Well, RAM as storage? Not really. However, I wouldn't mind seeing it as a RAID1. The reads would be scorchingly fast while the writes would be at hard drive speeds. For people with read-mostly access patterns, this would be a big win.
However, I'm waiting for the first system with a combined flash drive/hard drive storage system.
The flash system could be used for an initial cache and only wake the hard drive up intermittently for backup persistence or as a hedge against flash degradation.
