Leopard Incompatible Peripherals List

I was looking for a list of things that don't work at all, or well with Leopard, but can't seem to find much on the net, so I figured I'd start a list and let anyone else chime in from their personal experience.

Since I'm a little frustrated that I'll actually have to pay MORE for a used or new in box older macbook than I would for shiny new one with more RAM and more HD space from apple themselves, I'm trying to make sure that it's really necessary.

I mean, you'd want a thousand dollar toy to be able to do everything, right, but since I DO have a desktop at home, I'm considering just buying a new handicapped laptop and hoping the manufacturers of these devices come up with drivers that work sometime soon (although it's already been 6+ months).

• Mbox - some people can get it to work sporadically in Leopard, but Protools won't work (update 7/31/08 - newest protools upgrade - for pay - is now Leopard Compatible)
  
• Canon HD Firewire Camcorders (newer ones, since Novemeber of 2007 at least)
  
• Alesis Multimix
  
• Tascam FW-1082 (couldn't get it to work on Leopard, even after downgrading the firewire to the 10.4.x version)
  

What other things are people coming across?
