Looking for a mac notes app with folders/projects and iphone sync...

I am sure this must have been asked before but I have searched and can't find what I'm looking for.

Can anyone tell me if there is a good notes application that lets me organise notes into categories/projects/folders. I am looking for something that has both a mac and an iphone version and will sync multiple macs and iPhone over the web using mobile me for example.

I'm not looking for a task manager - I'm already using omnifocus for that and in an ideal world I am looking for something very similar to omnifocus but that is notes based rather than task based.

I'm not looking for a files/documents depository either - I use Evernote for that.

Just need simple text notes...

Any ideas? thanks.

Edit - I have found Soho Notes which basically does what I want, (mac client, iphone client, notes in folders, mobile me sync) but I find the interface a bit cheesy with all those icons...ideally looking for something a bit more minimalist - I like the look of Mori and Mark/space Notebook but they don't have iphone versions...

Edit2 - Having looked further into Soho Notes, there seems to be a lot of complaints about the syncing and corrupt databases...I have also looked at MacJournal which is along the lines of what I'm after but again quite a lot people having problems with the sync by the sound of it so still looking...

I appreciate the reply but as stated in my OP, I'm already using Evernote for other things and it's not really appropriate for my needs here, mainly because it uses tags rather than hierarchical notebooks/folders (I need hierachy) and it's kind of overkill - I don't need all the different file formats that Evernote supports, I just need text notes.

I think the nearest thing to what I want is MacJournal, but although it syncs to multiple Macs via Mobile Me, the iPhone Sync is unfortunately WiFi only.

I'm starting to come to the conclusion that what I want doesn't exist which I find really surprising - definitely a development opportunity here for someone I reckon!

Just to recap, I need:

• a simple text only notes application with Mac and iPhone versions
• Notes can be organised into folders and subfolders.
• Multiple macs and iPhone can sync via the cloud / Mobile Me

For anyone else's benefit who comes across this thread looking for the same thing...

Jesse Grosjean of Hog Bay Software is working on an App called PlainText that looks like it might be perfect - notes in folders and sync via DropBox - should be released soon...
