no, it's not boring. I for one, love the iPhone 5. I think the screen size is perfect. I've played with the Samsung Galaxy III, and I really couldn't see myself using that thing. The screen is big, which is nice -- but that's what my iPad is for. I don't need a massive screen in my pocket for when I'm on the go. I like the seamlessness and simplicity of iOS (and especially how it works with my iPad and Mac), and don't like how overloaded Android is with apps and what not from the cell phone providers. Not to mention OS updates that don't come out when they're released by Google, because the cell phone provider has to patch it through -- that's ridiculous.
If you want the bigger screen, then go get something else. I hope Apple doesn't give in to this idea of massive phones. I know it all comes down to making money, but it's not like they're losing money.
