CardBus CF

An interesting development: the first Compact Flash CardBus adaptor I've seen. Everything I've seen so far uses the older PCMCIA bus. PCMCIA (later renamed PC Card after too many jokes about People Can't Memorize Computer Industry Acronyms) is an implementation of the 16-bit ISA expansion bus in a small form factor. CardBus is more akin to the 32-bit PCI expansion bus, so it should be significantly faster.

Of course, the limiting factor with most CF cards is probably the slow speed of the Flash RAM, but with newer 32x/40x cards, as well as IBM MicroDrives, this could well speed the transmission of the 6- and 11-megapixel images generated from newer digital cameras.
