iPod touch apps...

• Weight watchers calculator AND tracker!
• shopping list (grocer-by category)
• games (tetris, sudoku)
• restaurant nutrition lists
• to do list (by urgency)

I normally have all this "stuff" on pieces of paper (except for the games) or on my computer (which doesn't fit in my purse - almost)

(the 5.5 is important to me because I've been looking for a calculator that will give me half points!)
