Got mine (Red, w/ Set of PBT Caps), liking it so far. May post pictures later, but my camera only just started working again.
Thoughts -
Definitely a different feel than my Filco Brown, both due to the linear/tactile and the plate mount. I know some haven't been able to notice the brown/red difference but I definitely feel the lack of a tactile bump for what it's worth. The keyboard itself is remarkably light but there's little flex even when you twist it - nothing to worry about. I'd say about as much as my Apple Bluetooth keyboard (maybe slightly more), which is part aluminum, and less than my Microsoft Bluetooth. The keycaps are pretty solidly attached - harder to remove caps than on a Filco, although Cherry-style stabilizers are simpler. I think I prefer the stabilizers on the Filco to the Cherry-style stabilizers. And the size is very nice - smallest keyboard I've ever had in terms of desk space. I'm happy with the construction overall apart from the lack of feet and nowhere to put the cable in transport, but those are minor complaints.
The default (non-PBT) keycaps are slightly translucent (which is nice). The Caps Lock window is completely clear and as a result the LED comes through really brightly. The Legends are nice and clear. They do feel a bit different, though - a bit "toyish" maybe? They don't quite have the solid feel that the PBT or Doubleshots have but I don't think they're a big concern. The PBTs are nice, although the legends are hard to read unless you're in a reasonably well lit area, relevant mostly for the lesser-used shortcuts. The feel is a bit unusual - textured but still a little slick. I don't know whether that's a coating or what; I'll see how it lasts but for now it's nice, as is the aesthetics. The board does come with a little instruction sheet showing the shortcuts and DIP switches so that's always usable as a reference if you can't quite see the PBT Fn layer easily. I tried using clears for the modifier keys, but the SP clears with soft-landing pads felt a little mushy on the reds, since the profiles were so low on the SP keycaps (certainly when compared to either the default or PBT Poker keys). So I went to using almost all PBT keys and I'm liking it more - less bottoming out and it's not mushy when I do. The drawback of the PBTs is it mutes the arrow-lock and escape-lock lights.
The main make or break with the board is always going to be the layout. After a few days the arrow keys are still somewhat awkward, since I used them more than I realized. Locking the right side (R-Win, Menu, R-Control, R-Shift) into arrow keys has been useful, but using "shift" has been somewhat annoying when switching back to using right shift normally; I wish they had placed a key to the right of the right shift; I guess they didn't to keep all the keys the standard size but it would solve most of my arrow key problems. I also swapped the Ctrl and CapsLock keys which I'm ambivalent on so far, but it's a dipswitch so nothing to worry about if you're not interested. The rest of the layout hasn't been giving me any problems, though I haven't done heavy use of the F-keys yet. The location of the delete key - Fn-z and Fn-/ - is easily superior to a standard keyboard, and the rest have been pretty much equal. There's no numpad on the function layer but I'm used to that anyway. I've kept the Left Winkey as a Fn key (another dipswitch; it can also be a Fn Layer lock).
It's too early for me to judge the red vs brown but I am kind of liking the linear action with minimal force. There's more than that in feel difference, but I'm switching from a plate-mounted brown with ABS doubleshots to a PCB-mounted red with PBT Engraved so there's bound to be a few gaps.
Overall I'm positive on it. I don't really see a problem when I use the F-keys (F1, F2, etc) more, so the big question is going to be whether I can get the hang of those arrow keys. I suppose I'll do an update in a couple weeks.
