Basically this.
Honestly, I wish they would have somehow combined Reminders, TextEdit, Stickies, and Notes into one single app.
Wasn't there a rumor that Apple tried to buy EverNote? This would be awesome. Especially if Siri could search/access it. You'd have an actual office assistant...
I tried using the apps for their original purposes but I could never remember where I stuck things so I ended up just sticking to Notes and just checking it frequently. If I need an actual reminder to do something iCal works fine for me.
To each their own, but I feel your pain.
One mans platitude is another mans....
