Rich,
Could you elaborate. Right now I think the jury is still out on these=20
devices. Personally, back in then 1970s I was under the impression that=20
magnetic disk drives were on the verge of being replaced, but they never =

came up with a decent reliable technology and price per byte. Now, with=20
netbook type devices, blades, space, density, power management, and=20
heat, I think there is pressure on the drive makers to come out with=20
solid state replacements for mechanical drives. Whether this is just=20
wishful thinking or reality I don't know.

Certainly there is a significant difference in the requirements of a=20
portable device, such as a netbook or laptop than there is for a high=20
density data center.
