'In case you haven't yet heard about Omea Pro, it's a unique new
environment for Windows (it runs on the .NET platform) that helps people
manage the barrage of incoming information that's a fact of working life
in the internet age. Until now, you needed different programs to read
e-mail, instant messages, newsgroup articles, and RSS/Atom feeds.
You needed still others to be able to organize web bookmarks, manage
contacts, and track and share tasks. Omea Pro handles all that and more.'
