Wow, what a difference in feel from the Model M. Much lighter and crisper. It even sounds a bit more typewriter'ish to my ears. The only thing I've noticed is a discrepancy between the force required to actuate the space bar and other keys. If I had to guess, it feels like it requires almost double the force. To anyone who has one, is this consistent with your experience? Is the space bar typically more firm than the rest of the keys?
