actually, in the world of casino games, all our devices boot from a cf flash. It's easy to replace when you have a failure, and you can make quick copys. High end cameras also still use these.
I don't get the point in this until everyone is shooting at 36+ mp jpg's. What I want to know is why they can't get their head out of the hole in the ground with the 128gb and 256gb micro sd cards for tablets and cell phones.
CF uses the IDE interface, so if these weren't crazy expensive they could be used with a $5 adapter from China in any PC that has a PATA port. I used to use one on a 486 laptop for giggles (Compaq LTE/25).
