For better or for worse, Sony Ericsson isn't exactly the first name that comes to mind for me when I think about smartphones. That's not to say that the company doesn't make quality handsets; it's just that I'm more familiar with the Walkman line of music phones and the Cyber-shot line of camera phones. Well, they've got a hot smartphone too and it is known as the Sony Ericsson XPERIA X1.
