I'm not trying to make *it* sound bad, I'm trying to make *me* sound 
concerned.  The more mission-critical it gets, the more important it is 
that you can count on it.  I DO believe that SSD drives will eventually 
take the place of mechanical hard drives.  It's a fun proof-of-concept 
right now to see them run rings around traditional hard drives in speed. I 
just want to see them get a bit more robust before I consider them ready 
for prime time.

I think that I've heard in normal PC applications a SSD will run for about 
5 years before going read-only.  My point is just that in the world of the 
i, it seems like the usage would be more intense, the cost-performance 
would be more of an issue, and the critical nature of the data would be 
more valuable.
