Yes, I would like to chime in...
I have never watched any fansubs, as I prefer to pay for and own my anime. I actually do enjoy the thrill of not really knowing about some of the series I buy. This does lead to hits (Gokusen, Mu Shi Shi) and misses (DearS, Shigurui).
I won't look down on anyone who watches fansubs, but they're just not for me. Besides, I like watching them on my large TV, rather than my PC monitor or laptop.
As for scanlations, I've (mostly) read series that are unlikely to be licensed and translated. I've read some great stuff on the Mango app for my android phone. Of course, I've considered reading Negima! that way, just because many of the earlier volumes are hard to find, and I already have a few 20+ volume series. There are some that I read the scanlation first, then bought the actual books/anime (Kashimashi, Ai Yori Aoshi).
I do find the lack of a printed page that I can really look closely at for details a bit of a downer, but for oddball titles, like Baka and Boing or Mysterious Girlfriend X, it'll have to do.
