I am looking into getting me a 3DSpaceNavigator, mostly because the device looks interesting (and I'm kinda fed up with the crappy drivers for my mouse/beginning mouse elbow), but what I'd like to know is:
Just for basic use of windows (Vista 64-bit), what functionality do I get?
Can I use it as a standard mouse on the desktop; what options do I have for assigning axis to different functions (back/forward in navigation, flip between windows, opening start menu, scrolling, etc)
And how is support for thunderbird and firefox - will it work as a normal mouse in those programs as well?
If someone coud point me in the right direction (I'm fairly certain I've missed it somewhere), or give the answers, that would be very nice

Thanks in advance,
Morten
