Yes, it has a display component. I don't see how that implies it must always be used by looking at it. Keys (usually) have labels on them, yet many people don't use the labels as reference once they're accustomed to touch typing. Learning key commands can be a chore, requiring use of the manual or discovery through menus. Do you remember cards provided with some applications that included lists of command key command…
You're missing the 'physical feedback' component. People don't need to look at labels on keys, because they can feel the keys. A smooth bit of touchscreen has no 'landmarks' to orient yourself with. > I completely agree that it is a new input device. Just not completely new Yep. Lenovo introduced one a couple of years ago in their X1 Carbons. It was hated so much that it was stripped out of the next gen. Ultimately,…
From the reading I've done this morning on the 2014 X1 Carbon (the only model that had the Adaptive Keyboard replacing the function row), there was a lot of dissatisfaction with the keyboard and trackpad as a whole, not only the strip. Among others, they removed the physical keys from the trackpad, moved the Home and End keys to the Caps Lock location, and removed other keys entirely. I read a lot of complaints about all of these, and all of these were reverted in the 2015 version.
Yeah, people are discussing the removal of the ESC key on the MacBook Pro as well. I'm personally going to miss the dedicated volume and brightness keys, and I use the ESC key in conjunction with Command to trigger LaunchBar, which I use heavily. I also think I'll be able to get used to it. There was a time in my life when I didn't use LaunchBar, and before I had dedicated volume and brightness keys. I don't remember it being all that bad. I'll see, when I get around to getting a new machine. I'm sure there are those who use the function row much more heavily than I. In the absence of aggregate data, I really can't comment on much more than my own experience and read about others.
Lenovo's decision to revert everything could be seen as them deciding it wasn't in their best interest to determine which changes were worth keeping. This is all speculation, of course. And they could very well have determined that all of the changes were ruinous to some degree. It's really pretty impressive that Lenovo was willing to make so many changes to their keyboard, when, AIUI, the keyboard is one of the features that keeps people coming back to Lenovo in general.
In the MacBook Pro, they're only replacing the function row with the Touch Bar. From an experimental point of view, it's a much more focussed experiment. It'll be interesting to see what happens when it's actually had more use.
