The new design sacrifices the 'X' hover-over on the left side of each tab, presumably in favor of an 'X' that overlaps the tab title.
I’m typically anti-touch screen on laptops as it drives the price up for a feature I personally almost never use, but there’s so many use cases particularly for a large portion of Apple’s user base working with digital media.
Aside: A Lenovo Yoga -like MacBook would be cool, although I do like the Touch Bar for quickly moving around in media I’m listening to in the background (but I don’t think that’s enough to justify it).
iOS started as an OS X variant with special consideration for touch, but forked Cocoa. The unification that’s happening now isn’t about bringing iOS to Macs, it’s about merging Cocoa-next back into upstream.
I’m not entirely joking - most of the Surface and iPad users I see at work are management/project-management.
Because it was designed by iOS people.
