which version of devonthink did you use? feflower Is sente worth the $90?
I use Devonthink all the time. Google Devonthink and you might find some personal anecdotes. I had the mid-level one and then upgraded to Pro Office because of the OCR capabilities; because I scan books, or pages of books, run them through the OCR, it avoids my typing in long passages from books. Scanning also is a pain, and I don't scan as much as I planned to; but after I do fieldwork, pick up a lot of paper literature, etc, I think I will be scanning more. Also most of my pdf/articles I download (I download mainly from JSTOR) are not searchable texts, meaning I need to OCR them if I want them to become searchable.
Again, it depends what your research involves. If you read a lot of research articles, annotate them, make notes from them: then Sente is good for you.
If you need to generate different bibliographies and find it a pain to do it manually, Sente will do it for you (with a bit of set up at the beginning).
When it comes to academic stuff, I don't skimp--I used to try and buy all my books, but now, I borrow them from the library--the money I save goes into productive apps like Devonthink, Sente, MacSpeech. Like all new apps, all of these need a little patience to make them work efficiently for you.
$90 for your "occupation" for the next 5 years is a small investment.
Take a look at this. It is dated, but will give you some other ideas.
