Yes? I take it that you don't? I have a few hundred CDs, DVDs, and Blu-rays that I like having access to. Generally, I'll access a floppy once, and just store an image on a USB drive for later use. My building is so jammed with wifi signals that sometimes the best option is to string an ethernet cable across the room, and the access point can't be configured over a wireless interface anyhow. I use serial and parallel connections (DB9 and DB25) to access various little hardware projects and pieces of network hardware I've got around.

I've got USB-based hardware for most of those. For others, I keep around some older computers. It feels "clean" to have a computer with fewer ports, but sometimes I wish I'd chosen a machine with a few more of the connections that my previous machine had.
