Well, with the release of 10.5.6 to developers and the addition of the trackpad icon in System Preferences, is there a possibility that Apple could release a wired or wireless trackpad to replace the Mighty Mouse. I'D BUY THAT 
I currently use my iPhone and an app called Snatch as a wireless trackpad. It's not perfect, but have to say, I like it a lot, and it sure beats the heck out of the rollerball that stops working every 2-3 months. There are other apps out there that do the same thing, but at the time (I'm not sure now), it was the only one with a 5 star rating (from 60+ users).
Thoughts anyone...
