Yeah, having 4 front facing usb ports would be a lot more useful than a zip drive.
The whole point of a portable media format is the fact that I can plug it in anywhere. No one uses Zip drives anymore, and their storage capacity is a lot lower than a usb drive.

Seems pretty obvious to me: replace it.

Although, currently, I'm strapped for cash. Here's what I plan to buy though:
