3DConnexion recently released their latest and greatest "3D Mouse" the SpacePilot Pro. I have been a long time user of their products - so much so I use to get stopped at airport security while they searched my bag to find a strange device with a solid aluminum base. My portable SpaceNavigator has as many miles in the air as I do since I can't leave home without it.
I am a big gadget guy (my wife can attest to that) so you can imagine my excitement when we got a few SpacePilot Pro's to play around with. I have been using it for about a month and have to say it's by far the most useful desktop 3D mouse I have used. I had the old Pilot and liked it although the screen was lost to me since I didn't really ever use it. With the new Pilot Pro I can see my Outlook calendar and task items (as well as standard Inventor commands) while I am working in Inventor. You can also display RSS feeds and use it as a Sideshow (Vista) screen where you can download many gadgets (it might be cool to show the weather).
Besides all of the neat extras, the buttons are clearly marked and for whatever reason I find myself using them much more than I have with any other device. I still like my trusty SpaceNavigator for notebooks but while I am in the office working, this is a must have for me. If you would like to know more about the SpacePilot Pro, head on over the 3D Connexion site.
