What I find interesting about the text mode is that even with the little bit of detail it actually captures, it is always esasy to know what is going on in the picture. Taking pictures of people it is always possible to see their expression and enough of what they are doing.
This is interesting as most people want their camera to capture more and more details because they think it will improve their pictures. In the end if you did not capture the decisive moment it does not matter how many tiny details are visible as it will never make a picture any better.
Using the text mode can be very rewarding as it makes one focus more on the composition and less on other things, at least this is what I found by using it so far.
