If early impressions are an indication, the Touch Bar on the new MacBook Pro is definitely not a gimmick. The time-saving feature lets you accomplish common tasks faster without needing to memorize a bunch of app-specific keyboard shortcuts.
Instead or remembering a shortcut or wasting time finding it in the menus, you just touch one of the system-wide or app-specific icons that are displayed on the Touch Bar.
For the hardware geeks among us, the more interesting aspect of the Touch Bar is the Apple-designed silicon behind it, dubbed the T1. As developer Steven Troughton-Smith has discovered, the Touch Bar is actually a mini Apple Watch.
