The trend is unmistakable: Smartphone screens are getting larger and larger. Where will it all end?

That was one of the questions addressed recently at CE Week in New York City. According to Mashable, which hosted a panel on "The Battle Over Smartphone Screen Size," it's impossible to buy a top Google Android phone these days with a screen smaller than 4.7 inches. Apple (NASDAQ:AAPL) is still lagging in this area -- its iPhone 5 finally stepped up to a 4-inch display -- but there's speculation it will have to go larger as well.

Our roving reporter Rex Moore was in New York, and spoke with Mashable's Lance Ulanoff about Apple's next step in screen size for the iPhone and iPad.
