I don't see the point of one gold key. Especially one that doesn't match the shape of the surrounding ones... and this is advertised as a "custom" made item. I believe this falls under the category of "save your money for something useful".

Why only 4? Btw, number 4 is considered as bad luck in Chinese culture :P

@eccentrix - The number 4 is selected because the shift key allows it to be a $ sign.

This idea is just dumb, honestly.

If you follow the link, you can read that "Gold Key $4 is custom made for your keyboard, hence development and production will take some time"

I assume that you have to sent your own key and they gold-plate it. So it fits perfect to your keyboard.

I think it's kinda funny, like an ironic gold tooth for your keyboard. But I'm not gonna detach my 4/$ key, ship it to Italy (Catalonia? Couldn't tell if you send it to the company or the designer himself, but VISCA DISSENY CATALÀ either way) and wait for it to get plated and sent back. A little too much effort for something that reminds me of those horrible stick-on "Any" keys that my stepdad found HI-LARIOUS when he first started computing, heh.

Plus I have a laptop and a funky weird ergonomic external keyboard, which is already so bizarre-looking that a gold key would just be a drop in the bucket.

Don't take this one too seriously, folks. Awesome!

It sounds like they're not plating the original key, but making a silver replacement for it and plating that silver one. However, if the one in the picture is a "matched" key for that keyboard, they're not making a very good match -- note the difference in the key's height and corner roundness, and in the digit's size.
