Today, Apple refreshed much of its entry-level laptop lineup in time for a "Back to School" push that includes slashed prices for educators and students as well as other perks, like a free pair of Beats headphones with certain Mac and iPad purchases. Additionally, the company discontinued the 12-inch MacBook and significantly cut prices of solid-state storage upgrade options across the Mac lineup, including in high-end models like the MacBook Pro and iMac Pro.

Previously, the 13-inch MacBook Pro lineup was divided into two categories: low-end, Touch Bar-free models, and higher-end models with Touch Bars. Now, every unit in the lineup is equipped with a Touch Bar, which brings into question some speculation by onlookers that Apple doesn't want to further invest in the Touch Bar.
