What are good family apps, like a multiuser shopping list app?

[naked]

I'm getting the iPhone 4 today, and I'm handing my 3G to my wife. What are some good apps that we can use together?

Is there a good app that will allow both of us to add to a shopping list?

Any other useful suggestions? We're definitely going to be using Words with Friends!

Multiuser lists and things, just use evernote, fantastic app!

Good shopping app

I've tried a bunch of grocery list applications and settled on Grocery IQ - it has a wireless sync function that works flawlessly between family iPhones.

We've also found 1Password to be really handy (use it between Mac, PC (beta version) and 2 iPhones). I think the developers are going to release wireless syncing of iPhones via dropbox (who have written an API to allow this).

There are tons. I love the key ring. You can add all your barcodes on there. Keep your Blockbuster, work out, Grocery store and any other barcode that you need close.
