I just realized that with my student discount, I can get the 17" for only $100 more than the normal 15" price. Now I plan to use the laptop for a few death by powerpoint classes, so it's not going to really be a laptop restricted to the house. That said, do the 17" laptops feel very awkward to carry around? Are there any other factors that should be considered when making the decision between the two? My friend told me that the 15" laptop has the new LED display, while the 17" does not. I have no idea what this means, could anyone please clarify? Do they have the same battery life? Essentially, if you could have either one for free, which would you pick?
