Like I said before I haven't used a K90, so at no point did I say it's a bad overall keyboard. Like that other guy said I was generalizing certain companies that in my opinion have the wrong priorities when making a product. And they could make keyboards that are a lot better if.
-If they cut down on the flashy things like back lighting( I also play and use a computer in the dark and I have never looked down and thought I wish my keys were lit up, because I can touch type)
-Stopped using cheaper parts (almost every razer product I have ever owned/used as felt so cheap and like it could break)
-And gave the choice in switches.
I'm glad you like your k90 and it works for you. Maybe I will pick one up if I ever need a new keyboard on another computer and try one out. :P
