Oh, I agree! I have also discovered the wonderful world of fonts- all the cool ones I can use for different things, such as lists or special asides to myself, and of course inserting images is a joy.
I had the opportunity to assist with beta-testing a wonderful journal-writing program called simply "The Journal"- and it was a lot of fun. It was also a nice feeling when the developer incorporated a few of my ideas into the program, such as text wrapping around images.
I have found that the spontaneity that I do miss about hand-writing my journal is well-compensated with all the fun stuff I can do digitally.
