i have tried this to see wether i can use it to take physics note or not. It tired out that this is perfect. however, during the demo, i have a problem about latex.
when i embed latex in note, it displays good. but when i open later, so many equations are just gone. I guess this is because notetaker handle the equations as attachment. and when i quit latexit, attachment names change and notetaker can not find it.
i hope the next update can fix this problem

Requires 10.5, not 10.4 as currently listed above.

I've used Notetaker for over five years, and every year I try out the latest edition of Circus Ponies NB. The functionality is nearly identical, as they share a common origin. I've never found a reason to switch to NB.

I use NT to manage large scientific projects, and link folders, programs, output logs, contact information, web sites, and Fetch droplets which link to remote Unix workstations. So, linking is important to me, and NT's linking capabilities are far superior to those of NB.

For example, in NT one can link files by copying (ctrl-c) in the Finder and pasting (ctrl-v) onto a page. This is measurably faster than dragging and dropping, which is NB's only way. In NT one can insert multiple links on the same line and mix them with text; one can drag an attachment to any spot on a page. NB did not have these capabilities the last time I looked at it.

NB now has the ability to tear off one page so that one can write in two portions of the notebook at one time; NT cannot do this--I wish it did (one can keep a copy open). Thus I give it four stars.

Over the years I've had a number of questions and suggestions for NT support; they've always answered promptly and helpfully. I would guess that one reason that AquaMinds chose not to have a forum is that their audience is very wide --ranging from school children who used shared notebooks (via the NoteShare product) to single-users like me. Also, I've seen small companies overwhelmed by
trying to maintain their forums. I'd rather they spent time on improving their products.

I've been using NoteTaker for quite a while now, and although it could use some improvement, I haven't found anything that does all that this app does. I teach, so I especially love the slideshow feature and the ability to post my notebooks to my website. It's clumsy on features (styles, fonts, multi-line), it needs tagging instead of (or in addition to) categories, but it's still very useful. I store documents so they're together with notes, thoughts, to-dos, mail (which i paste in). I've looked at Circus Ponies' Notebook. It's so much a clone of NoteTaker (which came first?) that I wonder why they don't marry their efforts. CP is marketing more aggressively and their website is better looking. Their product has a few features I like (more options in text features, different wallpapers) but not enough to make me switch away from Notetaker. Here's what's missing in both these programs: (1) better outlining - they should match some of the features of Omni Outliner (columns, notes) but leave off the complicated styling features, (2) calendar integration, (3) email integration. %80 of what comes across my desk is in email form. Why do I have to copy and paste emails between programs to keep mail, docs, notes, and calendar item in the same place. Yes, yes, I know: Entourage project. Hate it.

Charge much?
