Cons: Limited binding capability (new software on the way though). Not cordless! Notchy scroll wheel. It is small if you have Cyclops hands... but hey, I do have big shoes :P
Can you expand on this a bit more? What are they adding? Got a link with more information?

EDIT: Is this what you were referring too?
