Hi,I am going to buy sony 40ex503 in this month, but I did not get in touch this before, I am very interested in its internet function as I am using my laptop all the time. I want to connect my laptop to tv as I am a movie monster,and I alreay have a 2 meters hdmi cable. But after I research, seems like 40ex503 could plays computer movie through internet. now I alreay have a o2 wireless router, could 40EX503 connect and play movie through router, or I must buy a new sony UWABR100 dongle for it? and the dongle sale as 60 pounds that is too expensive for me, is it necessary to get one when I buy the new sony tv? Every suggestion will be welcomed. Thanks a lot.
