I'm not here to hijack this thread or anything but I created a group called 'iPad People' on Facebook this morning to discuss App Ideas. Or rather: to let ordinary people express their wishes for iPad Apps. Please consider joining the group, spreading the word & adding some ideas.

To prove that I do NOT want to hijack the thread here are all the ideas expressed in that group until now:

iShop: I'd like to have a nice shopping list app. iCal todo lists are just not as good. I think there's a whole collection of To-Do / Shopping / Productivity apps that can be built to fit this new form factor. The device encourages a little more interaction than the iPhone but still less than a full computer because of the lack of a decent keyboard.

iFingerpaint: .. for those spoiled kids who got the iToddler app! And for the grown ups a sketching app, and a photo editing app. Was actually preparing a submission for an iDoodle app or something similar to the existing iSteam app. I still like real paper for my brainstorming / doodling though. But the added screen real estate and multi-touch could give some nice interaction patterns, e.g. use the pinch move to crumble the piece of paper and toss it away.

iToddler / iAnnoyMyParents: Ever seen those platic toys with big colorful buttons that make funny sounds when your baby presses them? What about an app that has simple big icons, e.g. farm animals, a car, a plane, ... and when the child touches them with their hands it plays a sound / starts an animation. Guaranteed to drive parents crazy!

Offline Web Content Reader: Do you still print webpages for use in places where you don't have access to the internet? E.g. printing out a webpage or pdf for reading on the train / in the car? What about a simple web/pdf reader app that eats pdf or web archive files (created on your desktop with e.g. print-to-pdf or save-as-web-archive). You drop the files on the iPad app from your Desktop & the iPad can then display it offline in full gorgeous detail. I remember my Palm had such a sync feature now almost 10 years ago.

iClimb: What about an application where you post all of your climbed routes and share them with your friends? It would be nice to also post comments about the route, photo's, ... and a map to locate where the route is situated, so other climbers can get information about that specific route.

iShareMusic: The new SDK has easy file sharing built in. What about a combined Desktop/iPad app that scans your Desktop iTunes library & allows you to 'share' all of your music as a normal thumb drive instead of the annoying locked down iTunes connectivity. Want to copy music from a friends' iPad? Just plug in the iPad to your desktop computer, a thumb/usb drive mounts with all of the music on the device neatly organized in folders for easy copying. (DISCLAIMER: I'm not making any statements about the legality of this. Purely technical
discussion.)

iPad for board games: I think one first massive category of apps will be turn-based board games. People have been playing board games for centuries (Think Chess, Go, etc ...). The form-factor is really inviting: it's basically a gaming board on which you can play multiple games. But with a twist: multi-finger & multi-people gestures will allow some really interesting physical gameplay.
