Okay, Poker came in, in perfect condition (thanks manfaux!). Here's my 0.02:
The Poker with browns feels definitely different then the Filco. You can tell they're brown switches, but that's about it. Since the poker is PCB mounted, when you bottom out the keys (which I tend to do frequently), it feels much softer. Also, since there's no plate, the Poker feels much lighter weight. However, this thing is tiny. I mean I was actually a bit shocked when I took it out of the box. It's absolutely perfect for a compact travel keyboard.
I'm still getting used to the layout, but all in all, it's a great addition to my arsenal. I think I might try it at work tomorrow and see how it works out.
