I for one don't feel the need for an all-in-one communication app. I'm happy to use an app like Textual for IRC and Flamingo for IM.
I'm one of those people who do. For $10, if this thing included IRC, I would switch over in a heart beat. If it also included SKYPE? Oh man, the things I would do to the developer who made it...that would be heaven.
Less apps open usually means less memory consumption, and overall less clutter on my desktop.
