For this keyboard you can choose between Blue, Green, Red, Black and Brown switches. If you're looking for a familiar experience with an upgraded feel then the Browns are the way to go. With Browns you'll get quieter typing with a slight tactile bump. If you remember typing on old Dell keyboards from the early 90's and want to relive your clackity days, then give the lightweight Blues or heavier Greens a shot. The distinct click might get you frowns in the library, but it'll definitely get a conversation going in the office or at home. Those of you who like a super smooth typing feeling will prefer the lightweight Red or heavier Black as it provides a nontactile and silent type sound.
