No point in releasing iMovie for the iPad? LOL...oh man. Riiight. That nice big screen couldn't possibly be used for editing anything. Much better on the small screen of a phone.Guess what? My Mac-mini doesn't have a camera on it either and yet I still edit stuff with iMovie. And editing movies takes what to do???? That's right folks...it takes MEMORY.
Missing the point..
Your mac mini has input to capture video footage.
The iPhone uses it's camera for video footage.
iPad has no video capture or camera. So what exactly are you going to edit in iMovie?
