That is true. I hope they get some in stock at some point.
It has now been 13 hours since I acquired my RF87U55, and over half of that was spent away from the computer, but so far the only things I dislike about it are the keycaps on the Windows keys. I only use the left one, so I took the cap off that and swapped it with the menu key, which I also never use. But now my keyboard looks awkwardly asymmetrical. Good thing nobody ever looks at it.
