Ability to View Mind Map Software
I would vastly prefer using CloudOn for working with Mindjet MindManager maps than MindJet's single purpose cloud. I have all of them in Evernote today and just copy them out to view/edit on my iPad or iPhone (really rare on the iPhone though). Not awesome. But better than carrying my laptop everywhere just in case. That said, I get that there are far fewer mindmanager users than MS Office users out there.
