The Celeritas doesn't have any specific features to make it especially comfortable. It has the feel of an older style keyboard with clicky noises and clicky feel to confirm your keystroke. I think what made the keyboard a bit uncomfortable as opposed to rubber coated keys or a laptop style layout would be the space bar itself. The space bar has a rather harsh edge which, yes fits in with the style, but after some use makes you want to avoid using it. The space bar doesn't have the usual clicky sound like the other keys, as it is rather soft feeling and somewhat lacks the satisfaction for every press. With the space bar set aside the keyboard is just as comfortable as any stock keyboard.
