Tablets and MindMapping

Mindmapping is my preferred was to dump and capture my thoughts. I've been a longtime fan of Mindmanager by Mindjet. This wonderful software allows me to lay out projects and ideas in a non-linear, visual format. I can add color and symbols to flag significants items and with one click can export my work to Word, Powerpoint or Outlook.
But when I just want to free-flow ideas quickly, I find mindmapping on paper to be easier and more natural for some reason. There is something about the feel of pen on papera than seems to coax more ideas out of my brain.
Problem is, I then need to take those ideas and re-key them into my computer in order to take action on them.

Maybe this is the answer I've been looking for. I've been thinking about buying a tablet for awhile now. But wait a second-rumors are afoot about a soon-to-be announced Apple Tablet.
No harm in waiting a little bit longer...
