Thought I'd chime in on an old thread:
I have a G410 right now and I do really like the feel of the switches combined with the "normal" keycaps. I particularly like the high, tactile activation point, but others who are used to, say, mx blues, will probably find it jarring. I've always been a pretty light fingered touch typist, so it suits me just fine. The colors are bright and even, with nearly zero bleed under the caps, but I think yellows are a bit off. Personally, I would have been fine with a one-color illuminated board, so the RGB is a bonus for me anyway.
I don't care for the molded, one-handed wrist rest. I understand Logitech's logic here, but I think they're just outsmarting themselves. It isn't too bad, but it's just annoying that it's permanently molded into the case. I may break out a dremel and some plastic weld someday if it really starts grinding my gears. Speaking of the case, when you have the backlights turned down to a non-radioactive level, or even off, the board doesn't look too bad.
The keyboard also has some resonance and pinging which is a little unpleasant, but I think I may just be noticing it more because my work keyboard is topre. Regardless, I think I might try some damping material in the case.
In summation, if the only thing you didn't like about the G910 was the keycaps, then you'll be pleased with this board. I hope Logitech can put these switches in more professional looking boards--it'd be nice if they became widespread enough to justify some aftermarket keycaps.
