Sony Ericsson’s second-most exciting product announcement was the Xperia Pro – a high-end Xperia phone with a full slide-out QWERTY keyboard. It wasn’t much more than that, but they implemented a neat feature in their email application that’ll let you view your inbox in split panes. We’ll be heading out to the demo booths in a bit to get our hands on this and its cousins – the Xperia Play, Xperia Neo, and maybe the Xperia Arc.
