I just moved over from Remember the Milk and was pretty convinced this was the best option to integrate w/ the To Do app for the iPhone. I'm not completely in love w/ the set up of the Google gadget (which how I almost exclusively managed my RTM tasks), though. Like RTM, it would be nice to just have a "Delay" option for those tasks that I didn't get to in the day I had originally intended to do them (which is almost every day). With Toodledo it seems that you have to go in and change the date, which is a few extra clicks. I also don't love the large font, however, I saw another topic on how you can change it, so I plan to do that.
