I would second the addition on FW800.
Not all mini users are switchers or low-end buyers. The mini is also a good choice for semi-pro or hobbyist music makers, video editors, photographers, etc. who want the flexibility of a modular system but not the expense, size, or power consumption of a Mac Pro.
For example, I am an amateur musician and do a lot of recording. I recently bought Logic Pro. I'd like to get a mini as the hub of my project studio. I don't want an iMac because my studio would be better ergonomically with a separate monitor (I want to use an ergotron arm to suspend it above my recording desk). I don't need the size and bulk of a Mac Pro. The mini is basically the best option, except right now it maxes out at 3GB of RAM (not good for media apps). Faster firewire would be nice for streaming audio to disk.
So I've been eagerly awaiting an update to the mini. I am hopeful that Steve Jobs doesn't do something drastic like get rid of the optical drive (try loading all 7 discs in Logic Pro without one!) or, god forbid, dropping the firewire port (that's a deal breaker for digital audio). I hope he just updates the current mini with a faster chip, more RAM, 802.11n, and as a bonus FW800 would be nice. If they do that, Apple will have my money in a heartbeat.
