Looking for a Mac Note app?

I recently decided that it was about time to change the app I use to keep little clipping type notes for school, or little pictures or links because it hasn’t been updated in ages. That, and I never really liked it anyway.

But anyway, now I’m looking for a little information grabber type notepad app for somewhat heavy use. Preferably unobtrusive.

So all you Mactards out there, any suggestions? Running 10.5 Leopard on an Intel Machine, if that makes any difference.

For the record, the app I was using was Yojimbo. I’m looking for something similar, at least.
