Mindmapping I use MindNode pro on the mac which works with the touch version and for a quick map poplets which I can email. Don't have one on win7.
Do check out the forum threads though as there are a number of apps available.
Also have a look at zumocast, as not only does it convert and stream video to your iPad it can also view docs and photos on your desktop.
Very handy when you need to look something up in a hurry (without getting out of bed ).
sweeeet, definitely gonna get started on MindNode in the new year
