Got my new Panasonic 50 inch led tv yesterday and its superb.
Here's a good bit of advice for anyone looking to upgrade to a smart tv. My new tv is not smart, to have this function I would have had to pay around another £200, for a smart tv with the same spec as my Panasonic. I was also buying a new blue ray player, so the sales man advised me to pay an extra £20 to upgrade to a "smart" blueray player which also plays 3D blueray's, if your tv is 3D.
I didn't know you could get smart blue ray players. It works exactly the same as a smart tv and its got wifi built in!
