For those that use a Spacepilot, it will not work properly with SW2011. You will not be able to map the buttons the normal way. You will need to custom map each one using the 3DConnexion Control Panel in the start menu. Plus you will need to remap them each time you restart 2011. 3dConnexion was aware of this the middle of August but since 2011 wasn't released then, they chose not to do anything at the time. Now we'll see how long it takes them to get the driver updated. I do know that during beta I reported this but one user was able to use his without problems using an older driver but I can't access the beta forum anymore to find the version he was using.
