I need new notebook for following use : Making college presentations , writing thesis etc. Watching Movies Listening to Music Internet Surfing. Downloading movies / music etc. Now I am getting 2-3 laptops at very good price and need others thought on what would be the best deal , i know its very subjective but your thoughts are super welcome !!! In the following one I am getting 2nd gen i7 but am loosing out on 1600*900 resolution screen : Samsung NP300V5A-S0CIN Laptop (2nd Gen Ci7/ 6GB/ 1TB/ Win7 HP/ 1GB Graph): Flipkart.com: Compare, Review Samsung Notebook In this I am getting 1600*900 screen but only 3rd gen i5 Samsung NP550P5C-S01IN Laptop (3rd Gen Ci5/ 6GB/ 1TB/ Win7 HP/ 2GB Graph): Flipkart.com: Compare, Review Samsung Notebook In this I am getting 3rd gen i7 but am loosing out on windows and screen resolution : Asus K55VM-SX086D Laptop (3rd Gen Ci7/ 8GB/ 1TB/ DOS/ 2GB Graph): Flipkart.com: Compare, Review Asus Notebook Then there is a acer laptop in which i am getting 3rd gen i5, 1gb niveda 630 , 4gb ram , 750gb hdd and backlit kit ...this laptop is 7k cheaper than above models If I had to choose what should be better 3rd gen i5 with 1600*900 resolution or 2nd gen i7 and very reasonable price or 3rd gen i5 with back-lit keyboard or 3rd gen i7 but no windows. I am getting swayed towards laptop with backlit keyboard. How good 1600*900 resolution is over standard 720p , is it huge difference or negligible difference . If I had to choose between 1600 resolution and i7 what should it be. I need to listen to some opinions on what configuration to choose . FYI : I don't play games as such dosent matter if these laptops have good graphics or not ..
