oh and I wanted to add that Shake/Uninstall is great when you try an app (free mostly) and you want to uninstall. Just shake your phone and its gone.
I found ColorNote, sticky notes that you can put on your home screen. That works best for me because when I try to enter all types of info and stuff, its just too much. Notes are my best friend!
About Evernote, several of you have mentioned it but it confuses me. Are there "apps" for Evernote that you add to do to do lists and grocer lists?
For Evernote it's like you're creating notebooks. And for each notebook you can add lists, photos, notes, etc.
I started off using Evernote but now I think Springpad is easier.
