I wanted to know what enterprise apps do you use, if any?
what is an enterprise app ?
Yeah you'd have to be a bit more specific about that. From what I know this would usually refer to applications commonly used in enterprises (businesses), like office suites, email clients, groupware etc.
Well I use OpenOffice.org and sylpheed for the first two, but I don't really use groupware (except sometimes on the web, since wikis and even drupal sometimes count as groupware).
