Comment on Iris (by Nolobe)

I don't have Leopard, so I can't evaluate this app. But I'm curious why there ain't more people using this.

I think the interface looks very appealing in that it looks well layed out and everything seems to be housed in one window.

What's the impression of those Leopard users who've tried this? How does it compare to DrawIt, Acorn, Pixelmator, et. al.?
