Appropriate laptop for university?
So, I'm going into university this fall, for Science, and I'm looking to get a new laptop. I've done some research and I'm really into the Lenovo Ideapad U430 and the Lenovo Yoga 2 Pro.
I would like some more insight into these two, preferably from a student's POV, but any will be appreciated. I'm not a huge dead-set on tablet hybrids, but I wouldn't mind it. Generally, I'm just looking for good bang for my buck and decent battery life. Not a great gamer, but I do dabble in some PC games - Portal, Nancy Drew - so a laptop that holds up with that kind of stuff would be nice. I mostly surf the web (research) and watch/stream movies and TV shows, so it'd be nice if I had a device that didn't die after 2 seconds of media viewing.
I'm willing to do more research, but I'm also open to other devices, I've looked into the Asus Zenbook and I kind of like that as well (although I can't find it at any retailer!).
Any insight is appreciated, thanks in advance!
