i was on a thread similar to this last night for many hours and im going into first year life sci as well. From what i learned, you should get something along the following lines:
- Decent battery life (5 hours +). Most life sci. schedules i've seen usually have one day during the week where there's 4+ hours of class straight without any meaningful breaks. If you're planning on taking notes on the laptop...you should make sure that you'll actually be able to turn it on after using it for 3 straight cores
- The general consensus seems to be that everyone buying a new laptop for university should stay away from HP. Their service doesn't seem to be the greatest and many get the feeling that they're being built to barely outlast their warranty (which is usually for 1 year)
- The processor should be an i3 or i5. You don't need an i7 and stay away from anything with an AMD processor. You can literally fry an egg on anything with an AMD - that's how hot they get.
- Size wise, something around 13.3'' should be great. They'll be big enough to work on with some level of comfort, but small enough to fit in your bag along side your chem, bio, and math textbooks.
- Price wise... if you don't have a limit, it's great. Personally speaking, i really dont see the point in getting something over ~ $ 600.00. Every couple of years there's something much better on the market and Apple comes out with something new every time the sun shines on Silicon Valley.
In the end, you have to find something that's right for you.
In case you haven't found something yet, this is the one i'll probably end up going for:
