I went to bestbuy, only keyboard they had out was the razer widow ultimate, but sold corsair k700, and something from steelseries. I'm actually debating renewing mine only because I would love the extra desk spce.
Personally, I would go for the K70, but that's because I don't mind the linear switches. I think the switches on the Blackwidow are comparable to the Cherry MX blue switches, making that keyboard a better typing experience than the K70.
yea im really enjoying it right noiw. aand its completely customizable. i can download a piece of software and customize each key and also hyave 10 different profiles which is nice. it also allows the profile to automatically be set to a certain prfile if you set a game or program to it
