I've been drinking the OmniFocus Kool-Aid since it was in Alpha. That application has become such a part of my daily routine that losing it would have a similar emotional reaction on me to burning a 3-year old's favorite blanky in front of him. Nevertheless, I've been hearing a lot of positive things about the new kid on the block, Things. Several readers have happily switched over to Things saying it is not as complicated as OmniFocus. I use the hell out of OmniFocus so I'm not sure I could give up those advanced features. Nevertheless, for those interested, there is an excellent review of Things right here. Thanks to reader Landya for the link.
