Guys if any of you are planning to get 5 series, I'd suggest wait a bit. I think Samsung may launch new series S03 and S04 sometime soon. I found it accidentally.
See here : -
To find yourself, go to searchModel and type NP550 in the box and click search.
They haven't updated the website yet with those new models, but these models are in their database. I tried searching on the internet but no info is there about the newer models, so who knows what new features they might include in the newer ones. (I am hoping for a 17 incher and Full HD )
17 inch model starts with NP550P7C.
