I'm planning on purchasing a high performance multimedia laptop for college, and one of my requirements is that it has a touch screen, which severely limits the amount of laptops with full wattage i7s available to me. I also know low wattage ultrabooks generally have a longer battery life and are thinner, so I'd like to know if it would really matter if I got a low wattage one instead. I know the low wattage is dual core and has a slightly slower clock speed, but if I'm using the laptop for watching movies/tv, light gaming, programming, and light photo/video editing would it really matter? One other thing I'm looking for is a dedicated GPU, so the integrated GPU difference isn't a factor. I also want the laptop to last through the 4 years of college, so please consider it from a future-proofing standpoint also.
