Dell seems to really like "touch" buttons. The original XPS 13 had just a couple of them for volume and CD eject maybe and they continue to try to use them. They also used them on their monitors for WAY to long. I was disappointed to see them return on the whole function row of the XPS 13 Plus but at least there was the non-plus model with normal function row keys. But the "new" XPS 13 doesn't have this option. Why do they insist on pushing these crappy touch buttons? Touch makes sense for things you are looking at directly like on your phone screen. It's terrible for things you need to push but shouldn't be looking at like keys on a keyboard.
We picked up one of these new XPS 13s for a new employee recently and I was also a bit worried about the flat keyboard keys. But I also found they weren't that bad. They're not amazing and I still will always use my own keyboard over any laptop keyboard, but at least it wasn't terrible.
