Looking for my first ever Laptop.I like the larger screen size. Saw a couple in Comet today. SAMSUNG NP300E7A-A03UK 17.3" at £379 and the SAMSUNG NP300E7A-A04UK 17.3" at £479.94098, both 6GB ram, one dual core processor the dearer one i3,I would'nt be gaming or watching movies. I might occasionally use PhotoShop CS3. I'd still do most photo editing on my desktop PC. Neither have dedicated graphics so the cheaper model might be enough for me. Any thoughts, you experienced laptop users.
