Got mine in today, oh god I'm in love. I've been working with a first generation Das Keyboard for so long, but this thing is just a joy to type on, and the noise is orgasmic. The Das Keyboard has a slight "clank" to it that's just plastic-y, but the Poker is heavy and rigid from the plate inside it and all you hear is that glorious keyswitch action. There's a weight to the keyboard and absolutely no flex. The keycaps are nice and thick, easily readable, and personally I LOVE the font over the more common fonts used on keyboards. My only real complaint, and I struggle to even call it that, is that the printing is so thick on the keycap it does feel a little weird under your fingers at times, but I'm sure that will go away with time; still, I may look for a laser engraved keycap set if I could find one that can also do the ninja-print on the side. Not much else to say about it, it's a great solid keyboard that's delightful to type on.
Also, for anyone that's fighting the FlyT Tracking issue, I've noticed that they seem to cache earlier version of when they first ship stuff out. Do a force reload (Ctrl+Shift+R in Firefox) and it should show all the tracking details, at least it did for me.
