@Jeff - I posted this over at Toodledo in the thread you started there but thought it worth mentioning here also:

The fact that some issues will probably never be addressed because the developer only ever works on what "interests" him at the time left me looking around again. I've been using Appigo Todo on my iPhone for a few years and really like it. I tried out the latest version of their Todo Online cloud system and really liked it. Like the iPhone app, it has a nice balance of simplicity and elegance yet enough features to handle what I need.
So far so good!
