I showed up to a company wide strategy offsite with an iPad and whipped out a mind mapping tool. For the first ten minutes I could see my boss vibrating because he thought I was fucking around. By the end of the meeting he wanted a copy, and for me to CC his boss and a couple of his peers.
Which tool are you using on iPad?
XMind does have a couple of irritating bugs on Fedora around keyboard input (I can’t move focus with the cursor keys, it creates a new node) but it might be specific to my setup. Their support/developers don’t seem to care much, though.
