Great comment from Bob re an addiction he and I share-
Apps. Although I'm not sure if I'd call it a fetish but more of an obsessive thing. I'll pick up apps because they're free to try them out. Then I have a hard time getting rid of them, even if I'll never use them again or have another that does more or less the same thing but better.
I am trying though. I've cleaned out a number of games. I finally had a chance to really try the note taking apps I had and decided on Noteshelf as the best for me. I kept Notability because some of its capabilities are nice to have. I'm starting to get very picky with non-game apps. Otherwise there are just too many choices.
Sounds like I should be standing in front of the room and saying "Hi. I'm Bob and I'm an appaholic."
