This is very close to being a board I'd buy, but I think some changes are required;
1. Ditch the media keys. They're not necessary, there are plenty of other ways to control your PC, like a $6 remote which has the advantages of working from across the room and being something you can hide in a drawer when you're not using. The keys add clutter to the design of this board, which otherwise would look great.
2. Remove the logo. If I buy an expensive keyboard I already know what brand it is, I don't need advertising on my devices, thanks. At the very least, move it to the top left corner, maybe shrink it a bit. With a brand like Filco the logo is attractive and the name is something you don't mind people seeing. Corsair has neither of these qualities, so get rid of it please.
3. The font isn't terrible, but from some of the product shots the legends are... what? Stickered on? I'm not exactly an expert on cheap lettering techniques, but it looks pretty bad to me. Can we get some decent quality for our money please, Corsair?
EDIT: Ah, I forgot it's backlit. Some way to make translucent letters without using DS keys, I guess. Looks like my old G15 did, aka kind of cheap and nasty.
4. I much preferred the brighter brushed aluminium of the original K60, rather than this "gun metal" version. Maybe offer all three (with the black as well) with differnt LED colours for each?
5. More switch types. I know reds are great for gaming, but offering two or three switch options will increase the popularity of this board quite a bit, I think.
Credit to Corsair for making a TKL version though, and for the brushed metal/raised key design in the first place. All they need to do is get their act together with the details, and I'm sold. Maybe the next version will be improved a bit further.
