I'm on my second year of the OD subscription. In September I'll be renewing for a third. I find that almost all components of OD are useful. I use just about all of them; some more than others. What I do use every day are WB, OB and IP. When I'm feeling a little squirrely, I use DX.

Point is, for the three components I use the heck out of, it would have been $55 buy them all separately, but OD is only $50 for everything. It's a deal, if you ask me. This is software that is useful and yet doesn't impose on your day to day work/play.
