7 things that are on the iPhone but not on the iPad... Why?

This is a little peculiar to me - but I've become so used to my iPhone layout that now that I own an iPad - I feel myself looking for it on the iPad - but it's just not there. Why? It just seems natural that most things that you could have on your iPhone you should be able to have on your iPad right? Well here is the list of what I've found so far....

1. A Calcuator - yes this would be useful when I'm balancing my checkbook

2. The Weather - yes I know there are other apps out there that tell the weather ... But not as quickly and concisely as the one on the iPhone

3. Compass - as far as I know - you don't have to have cellular service for the compass - so what if I'm lost while reading on my iPad in the forest?

4. Stocks - I don't have any right now ... But still would be nice to see when Google crashes.

5. Voice Memo's - cause I like to talk to myself.

6. The ability to quickly access the camera - for that time I'm sitting at the cafe, drinking my latte and Madonna walks by.

7. HDR capability - kind of a cool feature on the phone - why not for the iPad?

This is just a small list - I'm sure I'll come across more - but the first two are REALLY irritating.
