ok i am a computer information systems major with a concentration in networking. i would like a laptop that could last me for the next 4-5 years and that can handle my workload. i have had 2 windows laptops (acer amd sony vaio) in the past 4 years and i am leaning towards a macbook but i don t want to spend all that money if there is a comparable pc option. also can you be specific with the recommendations. Thank you!
