Did you get free ear defenders with that? Nice keyboard - shame about the bleeding ears.
Anyway, nice keyboard but it would be wasted on me as I'm a hybrid touch typer (I have my own technique that doesn't appear in any textbooks). Any typing tutor will tell you that looking at the keys slows you down, but I trust people would want to look at that a lot more than my grubby old Microsoft Natural keyboard.
But, if you have the money, then why not? It's no different from people getting a QX9770 CPU over a Q6600. Aside from trumpeting your huge benchmark score, very few people actually
need the difference enough to justify the £900 price gap, but they still buy them.
