My company is currently evaluating the iPad 2 with more of a look to iWorks, email, cloud and other services / apps.
(fyi - having mem issues with larger files in iWorks apps)
In regards to your list and my world.....
Facetime - tried via the i4 and found it was pretty lame
Skype - don't use it
Webex - business has moved to Communicator
Fuze - don't use it
Boardbooks - moved to Sharepoint
Google Earth - don't use it
Word Lens - tried this in PR. didn't work so well
Hootsuite - don't use this
iMovie - not in my business
Popplet - don't use it
GarageBand - maybe for playtime?
Overall - not exactly what I picture as business apps, but areas do differ.
