Last week I mentioned a device that I would finally find useful for the ExpressCard slot in my MacBook Pro.

Some of the comments were interesting (and even rude), but obviously the original thrust of my anti-card slot comments were mis-interpreted. Years ago, I could fully understand why a PCMCIA slot would be useful, because the technology was modernizing all the time.

Today, most laptops come with a combination of built-in interfaces and the universal interfaces (USB, Firewire) that could be just as effective as the Express Card/PC Card slot for the types of devices we frequently use through the carded slot.
