I love buying software for my Mac and iOS devices.
What keeps me buying is often noticing I have a problem, and wanting to fix that.
I have kept a digital daily journal for about 12 years. I have typed more than 300,000 words, mostly detailing the things I did each day. I started entering text into a Palm device which slotted into a folding keyboard, then moved up to an Alphasmart keyboard which used the Palm OS: this was a truly fabulous device. I ADORED it. I later upgraded to an Alphasmart Dana. As the Alphasmarts had a full-size keyboard it was easy for me to stick to my discipline of entering text every night.
