Apple Touch Bar , Their answer to the touch screen laptop.
Apple has been firmly against the touch screen, choosing not to merge the ipad and the mac book. This is a big decision with big consequences. They have decided to incorporate a small touch screen into the keyboard. It will be interesting to see if this bet pays off as devices like the surface that blend the tablet and laptop are gaining popularity and market share. Will Apple stay stubborn or will the give in to what everyone else seems to be doing.
What’s really interesting about the new MacBook Pro running a mini Apple Watch is the possibilities for the future. Apple just added an embedded iOS computer with a touchscreen to its MacBook range, so that opens the doors for future experiments. “Today it might be similar to an Apple Watch in capability, but there’s so much potential for this to grow,” says Troughton-Smith. “The Touch Bar theoretically could run while the rest of the machine is turned off, so you get all the low-power and security benefits of an iOS device, without having to switch to ARM completely on the desktop.”
That could mean Apple could bring actual iOS features, apps, and touch functionality over to the Mac without having a true touchscreen. “Perhaps someday it could run a higher class processor, like Apple’s A-series chips, and allow macOS to ‘run’ iOS apps and Extensions, like iMessage apps, or manage notifications, system tasks, networking, during sleep, without having to power up the x86 CPU,” speculates Troughton-Smith. That possibility makes Apple’s Touch Bar experiment a lot more interesting, and it could make it a lot more like Microsoft’s failed attempt to popularize Windows SideShow, a way for developers to extend apps and notifications to small screens on laptops while they were powered off.
