Three years ago, my D started at her residential high school, which requires students to have a laptop, and they strongly advised buying an "industrial grade" machine through their purchasing program.
Her "industrial grade" Toshiba was in the shop six times over the three years - admittedly, two of those times were because of dumb things she did to it. On the other hand, I just retired a lowest-end Dell laptop I bought in 2006 and used extensively, that never burped once. The power brick finally failed, and since the computer (with its 40 GB drive) was out of gas anyway, I decided not to buy a new brick. I bought a $400 Acer to replace it.
