We mentioned using MindNode in a previous post: “Mind Mapping on the iPad Around the Home” One of the features we liked was that you could move the maps you create easily between the desktop app and the iPad app. The MindNode desktop software comes in a ‘free’ and a ‘pro’ (feature list) version. If you were hoping for the added power of the pro version, now might be the time to buy. We saw it on sale over on MacUpdate for the next four days (over this weekend). Not a huge discount, at 15% off, but drops it down to just over 20 bucks now.
