Great example of Apple's lack of attention to detail in iOS:

You're composing an email reply to which you'd like to add an image.

No problem. Copy the entire contents you've already written and then cancel the reply, deleting the draft.

Go to your photo roll, view the image you want to send and then click the send button, then pick email. Wait a few seconds until the mail process is started. Type the recipient's address - no, this will not be threaded as a reply. Type a subject (can you remember what the previous one was?) Now paste the contents of your clipboard above the image.

Want to attach another image? Send that email and start all over again with another image.

iOS email is beyond useless and I'd be surprised to hear it took anyone more than a couple of weeks to put it together.

Sparrow (third party email client) is honestly worth losing push notifications for.

Biggest hopes for iOS 6 - being able to hide or delete Apple pre-installed apps (not the frameworks if they're part of the OS) *AND* being able to define default apps to be used for core services, like web and email. Just like on the desktop (every desktop).
