How popular are the battery backed RAM drives that exist today? I don't
recall seeing them spoken about in this mailing list. The local geek
shop has these devices on sale. Are they still too expensive?

For those that don't know what I am talking about - they are PCI devices
that present themselves as a hard drive, but are filled with commodity
RAM instead of a magnetic platter, and a battery that lasts a few weeks
without external power.
