What's the sound of a tree falling when no one's around to hear it? What's the sound of one hand clapping? And perhaps most importantly, what's the purpose of a clipboard when only one app can use it? Development shop Proximi is making a pretty big stink about its MagicPad app for the iPhone, touting its homegrown copy / paste functionality as part of a rich text-editing package to help shore up the handset's weak sauce (read: non-existent) office app suite. That's all well and good -- the app looks well-executed and provides a core function that should've been present across the entire iPhone to start -- but without buy-in from Apple, the clipboard's stuck in the MagicPad sandbox. Cool? Yes. Should Apple be paying attention? Yes. Useful? At this point, barely.
