I bought one on release day. Got it now for a few days.
It's a nice wide keyboard, the keys feel nice to the touch and to press, better than my Saitek Eclipse II (and that was a very good keyboard!). The macro keys are fantastic and so its the software although not that many new games are supported by it (I had to create a StarCraft II and Bad Company 2 profile). Its got 18 fully programmable macro keys and if you can be bothered to program them it is absolutely amazing! The ilumination is fantastic though, although not as strong as with the saitek, its not variable either but that doesn't bother me at all.
The only issue with the keyboard I have is that its quite flat and feels funny when typing but I am pretty sure I will get used to this.
If you can wait two days, I can give you a few real life shots of the keyboard on my desk.
I paid £75 but that was a once off offer. I think it is a really good keyboard but I am not sure its worth £90 or even £80 - £50 or £60 sounds more like it seeing as its not mechanical. If I was to pay the full £90 I would probably wait for that Razer mechanical one which will cost around £120 and go the full circle!
