Anyone using a Mind Mapping App they like on the Surface Pro? On my desktop, I use 2 - Xmind for my own brainstorming and Wisemapping for ones I need to share with clients (web-based). I want one for my Surface Pro 3 that I can use when facilitating brainstorming sessions with groups. I dislike relying on web-based tools when doing these sessions as the wireless connections can be spotty in some facilities. Xmind is awesome but slow to load and I am worried it would be too resource intense for the Surface Pro 3. So I thought an app might work better. Any ideas?
