Reliability issues aside, yea right - over the dead bodies of the 
current drive manufacturers.

OTOH, 25c per GB vs $5+ per GB...

OTGH... Have you checked the spot price for memory chips recently? 
It's firmly *below* manufacturing cost.  Many of the memory 
manufacturers are now on the verge of bankruptsy shutdown.  They're 
asking their governments for billions in assistance.  If that market 
collapses...  This has mostly been reported in the tech sector.  I 
expect it will hit the "main stream" media when MS asks Uncle to chip 
in a few hundred billion, so they don't loose their investment. 
MSFT, being a DOW stock, can't be allowed to tank out.

Really tho... it's time for a slight paraduck shift.  For decades, 
tape drives then terminals and other input devices emulated card 
reader / punches.  Now we're going down that same road with hard 
drives.  WHY are we screwing around emulating disk drives with 
memory?  That's so last century!  Just map the memory in-total: Use 
high speed cache for the first n MB.  Then SDRAM for the next n GB. 
Then some non-volatile RAM ("flash" of one type or another) for the 
next n YB.
