Not everyone can use a trackpad.
I’m curious: when would someone be able to use a touchscreen to pinch to zoom, but not be able to use a trackpad to make the same gesture? Is this an accessibility issue or just a question of what hardware is present?
I too assume touch based Macs are coming at some point. But I expect them to live alongside conventional laptops for as long as people continue to buy them. Whenever I’ve tried different kind of convertibles they’ve felt like compromises. The tablet and the laptop seem like the best version of each.
