The mangling of what should be proper, full sized, inverted-T cursor keys is one of the most damning usability and user experience things of recent years. First the arrow keys got shortened to be half-height so they could fit them into one row. That was bad enough. But then the real kicker that I just cannot fathom is when they made the left & right arrow keys full-height, and had the up & down arrow keys half-height inline on the same row. This meant there was no negative space to afford touch feedback, which meant it was a lot harder to find and use the keys without looking at the keyboard, and that even when using them one could easily get off-by-one or more.
Ok, well, then the extra double-plus serious freakin' kicker to that kicker is that not only is this happening on business laptops, but... shudder... on (so-called) gaming laptops. The sky truly is falling.
