So far, so good with blue.....

The ambient noise in the office pretty much keeps the loud chattering characteristics of the blue switches in check.  It provides some relief to the constant machine droning and bursts of the activities around.  The clicky noise is not as pronounced in a larger room, I suppose.  Thus, as long as someone around doesn't complain about it, this keyboard will stick around for a while.

The keystrokes of the blue switches have more of a bounce in its return action.  The tactile feedback is much more pronounced than the brown switches, as the blue one is designed for both clicky sound and the tactile feedback.  The high-pitch shriek is still present, but as I said before, I am getting more used to it and are starting to simply tuning it out.  If that noise can be dampened out, perhaps it will be more welcomed.  For the work computer, the media keys are largely useless since I don't use this particular computer for much media consumption.  Maybe if I decide to take this one back home, it will be more useful.  For now, the media keys are superfluous.  The big volume knob is till pretty cool tho.....

The typing action of the blue switches is breezy and fairly smooth besides the click portion.  It does take a bit more effort to press the key compared to the brown switches.  The key activation point is fairly close to the end of the click.  Unlike the brown switches, which the reset point is very close to the activation point, its reset point is rather far away from the activation point, about 1.5mm or so.  So, once the key is activated, it must travel some distance before it is reset and ready for another stroke.  WASD Keyboard has some very nice force-distance curves for the various type of Cherry MX switches.  Checking the force-distance curve will show what I have observed thus far.  The short activation to reset point of the brown switch allows it to reactivate more quickly while the blue switch will have to get through a larger deactivation zone and the user will have to wait before it will register another keystroke.  Thus, the blue switch has to bounce further back up before it can be activated again.  This is probably to prevent accidental rekeying, which is important for accuracy.

Therefore, it is reasonable to say that the brown switches are more well suited for quick repeat action on the same key whereas the blue ones need more time to ensure that its activation is more intentional.  For normal typing scenario, the activation to reset action difference probably doesn't matter much.  However, if someone is playing a computer game, then the time-out period the blue switches need is more likely to become a matter of victory or defeat.
