I don't care much for the fancy backlighting. Backlighting is good, but I'm pretty utilitarian. I see no need for the lights -- but if you're into that sort of thing, it might be good for you.
The big sell for this keyboard isis, of course, its use of Cherry MX Keys; You should weigh your options before choosing which to get; Look online for more information -- many reviews take the time to discuss the differences.
My main complaint is the spacebar; It seems a bit dodgy depending on how you apply pressure; Maybe it's just me, but I don't like it; They also ONLY give you the special texturized key for this one, no regular spacebar, so be aware of that; I don't go for the texturized WASD etc.
