First of all somebody mentioned tits. Which are good. And AFAIK all tits are ergonomically designed.
As for keyboards, Viper and Eagle are pretty sweet.
Those GON's are totally sweet. In fact, I think I have to say they are in fact "schweet".
And the HHKB Pro 2 Type-S is by far the best keyboard in the world. Although you really have to try the others to understand this fact.
So - if money is no object, you should get them all. Get a GON, a Poker 2, and an HHKB. Probably should order a Viper and Eagle too. Eventually however, you will sell off all the MX keyboards, and just keep the HHKB. You could save yourself the money and just get the HHKB right now and be done with it. But you won't. And why should you? You are rich and sexy.
