I used Inspiration for maybe 10 years ago, but had to abandon it for some reason.
Now it was time to try it again, and I've been missing its unique feature to easy switch between outline view and mindmap.

It is really easy to use, and works well.

But it's shortcomings is the limited import and export, more crippled than limited.

I cannot find any way tom exchange information in an useful format. No import of mindmaps from other software. At least the ability to import/export to Freemind. As long as the import/export is so crippled Inspiration is of no use to me, and I would really love to use it again.
This feature alone gives the low rating.

Really love this one. Just some things that can be further developed.
1: note isn't saved unless you choose to or choose another note.
2: Using Slashes in note name is not a good idea as it will reflect in the path
3: I'd really really would love the possibility to make links to other notes (and sort of make a mini-wiki)
5: If there was a possibility to sync with other notes and from there to the iPhone...
4: Other things I've thought about, but mostly i just like having Sidenote on the side of my screen

Does the world need more spam utilities? Is there a way to forbid them? (and give corporal punishment to whoever distributes them)

I also had problems viewing the demo, but changing the user agent to Explorer 7 helped.
Pity that M$ doesn't provide a way to easily send feedback on this beta (isn't that what a public beta is good for ;-)
