As per David Allen's palm setup, he puts his Someday/Maybe list on his To-Do list. I'm just wondering how it's different from his other Memo Lists such as Maybe Get, Next Time In, Ideas???, etc.? Aren't those someday/maybe also? What's the distinction? I'm thinking DA's someday/maybe list would be more like deferred projects instead of someday/maybe.
Also, why would it be better to put the someday/maybe list in To-Do's along side the projects list? Why not put it on Memo along with other someday/maybe's?
