Sony CEO Howard Stringer began a [Consumer Electronics Show 2011] press preview by pointing out that by March of this year his company will have enabled 50 million Internet-connected televisions through Google TV, the PS3 or its Wi-Fi connected Blu-ray player. But, the device that caught my eye was the Sony Erickson Xperia arc, a very pretty new smart phone that lets you watch movies on its 4.2-inch touch screen. If you happen to be watching a film on the train home from work and haven’t finished at the end of the commute, you’ll be able to connect your phone to your TV at home and finish watching on the big screen.
