We have a lot of Toughbooks, Thinkpads and Lattitudes at the office that hit 4+ years. Almost all have a dead battery or in the case of desktop use about 50 to 70% capacity of a new battery so life span is not all about make. Use and care are a big deal. If they sit on a desk they seem to last for years. Those that are used by students with daily travel almost always need repairs in year 3 and on.
So I am looking for a laptop for grad work, streaming, and photography. But here is the tough part: I want a reliable brand with a long lifespan! (The only reason I have considered macbook is because they are said to last longer than the typical 4/5 years.)
Currently considering Asus N500JV, maybe a mac, or a Lenovo...
Advice is more than appreciated!
