I'm a bit surprised by most people here focusing on the wrong things. I don't particularly care if a keyboard is the ugliest thing ever (omg it is), or what the target market is (eh, I sometimes fit), or whether 'cracks' fit on it (rofl), or even what the layout is (to a certain extent). What I primarily care about is the switch - and if you happen to recall which switches I prefer, you'd know this to be true.
What Omron and Logitech have done here is make a brand new keyswitch, which is a far cry from what Razer did for example, where they didn't even bother to clone a clone., but merely rebadge. Although while with all due credit Matias has made a superb switch offering improving upon the status quo, their switch is also a clone of the ALPS switches. So, once again, we have Omron which has a history of making quality switches (including keyswitches) create an entirely new keyswitch, with specific and rather different accommodation for backlighting at that. That's very exciting.
So, maybe they really did make some special and awesome switch, maybe not, but I feel that this should be the primary metric upon which the keyboard is judged by us. Even if Logitech doesn't particularly care about us as a marketing demographic, as otherwise pointed out earlier in the thread.
