Macs have never really been appropriate for embedded computation, and it doesn't come up much in practice. I work with people who work with lab software which is happily running OS X 10.2 Jaguar. It's no different than the XP box in the corner, as long as everyone understands that the checkbook has to come out when it breaks. On the other hand, the quarter million dollar cytometer is going to be running Windows NT 4 Embedded, and when that ATA-66 hard drive fails or the software becomes unable to talk properly with the modern world anymore, it's on the vendor to make it work again. The support typically blows, but it's their problem to handle and none of them are going to be relying on Apple's memory-hole platform.
