I do like the lightness of the ultrabooks. Battery life isn't a huge issue as Im generally able to plug in where im going but ~5 hours wouldn't hurt. I'm willing to accept eGPU as an option as I was looking at those as a way to keep the laptop current into the future and upgrade towards the 20xx series in the future. I'd like to be able to play newer titles on the go (Rise of the Tomb Raider, Metro, Hitman, etc)
