i have a sony ericsson xperia x2 (my third one, i think. just love this phone!). when i was still teaching, i used to hook it up to a projector via the tv out port and give a visual presentation of my lectures. now, it's just a back-up phone which i sometimes use to watch videos on a bigger tv screen via the tv out port.
unfortunately for my x2, it has been replaced by my xperia p as my daily driver.
