I believe that this is being a little over hyped as we have had systems running such OS's as linux and embedded linux in the topend PMP and alike using memory only storage for quite a while and they seem to survive.

I guess time will tell really
There are ways to tune the OS around the problem. Use lots of RAM and disable the swap file, is the most common. As SSD's get much cheaper, they will become mainstream. Right now a 80 GB SSD cost around $300 US. I bought an 80 GB hard drive for my Linux experiment for $35 (on sale at newegg, with free shipping.) When 80 GB SSD's get to $35, I'll use them instead of hard drive, and tune accordingly. Until then....
